I tried fiddling with the magnification ring as well as the diopter to yield a better two eyes open experience. I was unable to get as good a merging of the images as many of the other scopes in my testing provided. I do not remember if bumping the mag yielded a flatter field of view specifically having magnification in one eye but not the other causes enough problems on its own that flattening things out would not solve anything if that is how it must be done.

Jim - Talking to the custom shop at Leupold...running into the same thing someone else brought up. Other than the multi-gun, doesn't look like (they think) they can do a special order on the VX-6 1x6 or 2x12.

Couple of questions...do you know if they can do the SPR on the 2x12?

Do you have any info on who to talk to that knows more about the 1x6 and the SPR?

Thx


I wrote the Leupold rep concerning these questions. Here is the response:

Right now the custom shop is not doing any special orders on the VX-6’s. Generally speaking there is a 1-2 year wait time on newly introduced products before we are able to offer major customizations due to production demand. The custom shop can currently do external modifications such as engravings and CDS dials, but will not be offering “special builds” until later in the year / early 2013.


The second part of the question: when the Custom Shop does start offering custom builds and modifications on the VX-6 series they should be able to install the FireDot SPR from the 1-6 in the 2-12, but the subtensions will not be correct due to the difference in magnification. Also, due to the design differences between the 6x system of the VX-6 and all other current production scopes, when the Custom Shop is able to do reticle swaps they will only be able to update with the reticles currently available in VX-6’s, or built specifically for VX-6’s. Another question we get is “Can you install Mark 6 reticles in the VX-6?” and the answer is no, because the erector systems are built differently and the Mark 6’s are FFP and the VX-6 is SFP.


Your prayers were answered.
DSG Arms just sent out an email listing the Leupold VX6 1-6 "Multigun" which has the SPR Firedot reticle installed. And its only $950. Actually says "Multigun" on the side of the scope.

Now if only they could do it without the flashy gold bling and bright white lettering....

Maybe I'm asking for too much. ;)

Review of the Nikon M-223 1-4x scope with Point Blank Reticle.

By Les (Jim) Fischer (BigJimFish on AR15.com and SnipersHide)
July 2, 2012


I was a bit surprised when Nikon decided to send me this M-223 along with the Premier 8x20mm binoculars I had asked to review. I did a Shot show report on this optic and was less than kind. I didn't expect they would be keen to have me write about it again. Shot show reports are cursory, though, and hands-on evaluations include more in-depth assessment of the optics, as well as testing of the adjustments, close quarters speed, and a number of other aspects of performance. Nikon was banking on the strength of their optics performance to offset some of my initial impressions. It turns out to be a good bet. While I haven't changed my mind regarding many of the misguided features of this scope, it does perform solidly.

Here is the Nikon M-223 mounted on my 16" AR:



Due to Nikon's long loan time for reviews, it has been present for and included in the lineup of two sets of scope reviews.

The first lineup, from top to bottom:

Leupold CQ/T
GRSC Japanese-made 1-6x
US Optics SN-3 3.2-17x
Nikon M-223 1-4x
Elcan Specter DR 1/4x
GRSC Korean-made 1-4x (prototype)
Leupold VX-6 1-6x



The second and more price appropriate lineup, from top to bottom:

Nikon M-223 1-4x
GRSC Korean-made 1-4x (prototype)
GRSC Japanese-made 1-6x
Firefield 1-6x24

Background:
Nikon is a very big fish in the small pool of sport optics. It is probably well over twice the size of the next largest optics company, provided its camera and semiconductor divisions are not ignored. This gives Nikon an economy of scale that is unrivaled, but also adds the liability of a slow moving bureaucracy filled with many people who have little to no knowledge of needs of the specific markets for which products are intended. This scope is a perfect product of these realities. It is optically and mechanically very good, better than its competitors at its price, but the lack of understanding regarding of the needs of an AR optic is also present. It has sniper knobs, a poor and bulky reticle, and a lack of illumination.

Physical Description: The M-223 is long and slender with incongruously bulky exposed adjustments. Much of this length is not actually part of the optic, but rather a defacto sunshade consisting of roughly two inches of main tube extending beyond the objective lens. This may explain some of the optic's excellent anti-glare performance. The machining and fit of the M-223 is generally very good, though the power change ring has a finish that does not match the rest of the optic and looks rather cheap and cast. At 13.93oz, the M-223 is one of the lightest scopes in the table, which will be approved of by the weight conscious. Included in the box with the scope along with the requisite paperwork are flip up scope capes. They are not Butler Creek, but are of good quality and should hold up. They are certainly preferred to the scope bra many makers include. A mount is not included with the M-223, though SWFA does sell a kit for an extra $40 that includes a Burris P.E.P.R. mount. This is a good value and you are not missing anything skipping the M-223 mount. It is functional and of reasonable quality, but it has a slow and less than elegant multi-piece base and would not be my choice at its $80-$100 price point. In my testing I am constantly moving scopes about and the M-223 mount, with its multi-piece rail attachment, does not win any points with me.

The M-223 in mount with box:



Reticle: The reticle is a disaster. Imagine your standard duplex reticle, but shrink the thin section in the center to half the normal size and then put a big dot right in the middle to defeat the purpose of having the thin section in the duplex by obscuring the aiming point. The thinking behind the reticle seems to have been to make it big and thick so that you can't lose it. Perhaps this has something to do with the lack of an illumination feature and low light use, but more likely the designer just thought that big and thick was easier to see and therefore faster. The thinking is not correct. Large, thick reticles are not faster at close quarters. My CQB testing has been unequivocal on this point. Thick duplex reticles are consistently ranked among the slowest. The fact is that it does not seem to be the reticle, but rather the target that is more important to see. All that reticle just covers the target up. I should also mention at this point that the duplex reticle in the M-223 is of little help in ranging and drop compensation. Most, though not all, AR reticles make some effort towards these ends. While I am not convinced that a ranging reticle is essential for an AR optic or even desirable in all cases, I am quite certain that to justify the giant, sniper rifle styled, exposed adjustments present on the M-223, you must have one.

Comparative Optical Evaluation: The Nikon M-223 performs better optically than most scopes at its price point. With regards to clarity, it is much closer to the $1025 Japanese GRSC 1-6x that is manufactured by, and therefore representative of, the many Light Optics made scopes in this price range than it is to the $350 Korean made GRSC 1-4x. I wonder how its optics would compare to the $500 Vortex Viper PST scopes. I no longer have one to compare it to, but I suspect that this might be a fair fight. In addition to good clarity, the Nikon is also very good at handling stray light and difficult lighting situations. Even when held at the most problematic angles to the sun, it is quite useable; unaffected even. Perhaps this ability stems from the unusual integrated sunshade composed of the last two inches or so of the main tube. Field of view of the M-223 is less than exceptional. It is comparable to the Japanese GRSC, on the low end of average. Nikon's great experience designing optics shows in the M-223: it outperforms its price bracket.

Exit Pupil and Eyebox Discussion:
I have recently had to re-evaluate my take on eyebox and Exit Pupil. The exit pupil is the size of the disc of light at the point at which it is focused for your eye. Assuming you are using this scope for close quarters work and you are moving about: your head will not be completely stationary regardless of how good your cheek weld is. A larger exit pupil will allow you to keep view of the object through the scope despite your movement, though it is notable that due to parallax error, the reticle will not be exactly where it should be when your head is far off center. People refer to the range through which your eye can move about and still get a good image as the "eyebox". As you can see below, the Nikon M-223 has a mammoth exit pupil and, therefore, a mammoth eyebox. Conversely, the Specter DR has a very small exit pupil. It is so much smaller that the area of the Nikon exit pupil is almost 4.5 times that of the Elcan. It has been my thinking in the past that a larger exit pupil would translate into vastly more forgiving head positioning during use and therefore greater speed when movement is involved. In my practice though, neither the cost of an optic, nor its speed when tested at close quarters has correlated well with exit pupil. This could have something do with the unmeasured axial component of eyebox, but I am not overly convinced of that. While I have noticed some greater forgiveness in eye position in the larger exit pupil scopes, it does not seem to be of much importance unless compared with scopes that are unusually constricted. It seems that as your head naturally centers itself behind the optic it adjusts very rapidly to the demands of each optic. Provided those demands are not unreasonable, this process does not seem to be overly faster in a large exit pupil scope than a moderate one. Also, red dot type scopes, which do not have eyebox limitations, have not proven to have a significant advantage in speed throughout my testing relative to conventional scopes, though I have not tested several examples to determine brand differences at this time.

In summary, the M-223 has a very generous exit pupil. This is to its credit, though I do not think that that credit is as large as I once did.

Exit pupil measurement setup:



Exit Pupil measurements of the scopes that I have tested arranged from largest to smallest:

Nikon M-223 1x, 16.7mm, 4x, 5.3mm
Firefield 1-6x ffp 1x, 16.2mm, 4x, 4.6mm
Viper PST 1x, 16mm 4x, 6.4mm
Razor HD 1x ,13.2mm 4x, 6.5mm
GRSC K 1x, 13.1mm 4x, 6.7mm
GRSCJ 1x, 11.2mm 6x, 4.6mm
Leupold VX-6 1x, 10.7mm, 6x, 4.4mm
Elcan Specter DR 1x, 8.0mm 4x, 7.4mm
Leupold CQ/T 1x, 9mm 3x 4.86mm


Illumination Subjective and Comparative Evaluation: At this juncture I usually discuss the illumination system of the optic in question and compare it to that of its peers. Despite the lack of illumination capability in the M-223, I have elected to keep a small section here to remind the reader of the almost ubiquitous presence of illumination in optics competing with the M-223. I was surprised that, in designing an optic specifically for the AR platform, Nikon did not include illumination. I have chosen to include the M-223 in my table and to write a review of it despite this fact and it is the only optic that I have made that exception for. I do this because of its popularity and in deference to the largest riflescope company in the world.

Mechanical Testing and Turret Discussion: Power change and box tests are designed to test the accuracy, repeatability, and independent nature of a scope's adjustments. In the box test, the shooter aims at the same place when firing all shots, but moves the adjustments between groups such that a box is formed by the groups fired. The power change test is performed by firing a group at each end of the power range of the scope without moving the adjustments. Each group is fired at a different target and any shift in the position of the groups indicates a shift in the point of aim when the power is changed. Theoretically, front focal plane scopes will not show a shift in the groups while second focal plane scopes will. The magnitude of the shift will dependent of several factors, including how far from centered the adjustments of the scope are after being zeroed. In practice, almost all scopes I have tested have shown a shift in point of aim when the power is changed. These tests are done using a BKL adaptor on an Anschutz .22lr. This provides very small groups and therefore good resolution while maintaining minimal ammunition costs to yours truly.

M-223 box test:



M-223 power change test:



The Nikon M-223 box test is slightly different than ones I have done in the past. This time I started in the lower left corner instead of the upper left. I also moved the adjustments 4 inches at 25 yards (16 s-moa) instead of the typical 3 inches at 25 yards. I started at the bottom of the box because the scope had been adjusted far down from its center due to a mount with built-in MOA and I didn't want to run out of elevation travel. In any case, the box test was perfect. The adjustments are accurate and independent.

The power change test showed a shift in point of aim of 1-2" at 100 yards. Given that this is a second focal plane scope that, as I mentioned before, had its adjustments far from centered due to the angled base; I consider this an excellent result.

Comment on Adjustments: The adjustments on the M-223 are large and exposed. They protrude roughly .9" from the tube and are almost 1.3" in diameter. The 1/4 inches per hundred yards clicks are satisfyingly audible and tactile. Each knob offers 20 s-MOA per revolution and the zero can be reset by pulling up the knob which disengages it from the screw. You will be pleased to learn that the knob indexes properly at each hash mark and also can be set at any hash. This has recently been a problem on some brands' long range scopes. I mention long range optics because that is the kind of optic these adjustments belong on. They are well suited to a scope with ranging capability that requires drop compensation via the adjustments. This scope lacks these features. On the M-223, the knobs are just oversized and, being exposed, will be subject to accidental adjustment. One last thing to mention before leaving the adjustments is the sticker on the ocular housing of the M-223 that proudly proclaims "Precision AR Optic Ballistically Matched." As mentioned before, the reticle is a duplex and therefore not matched to any combination of rifle, cartridge, and load. Similarly, the adjustments do not bear any markings that could justify this assertion. I consider this sticker to be false advertising as the words "ballistically matched" do have meaning and this scope makes no attempt to fulfill that meaning.

Close Quarters Testing: This is a fairly new section in my reviews. I have received many requests for my opinion regarding which optics are the fastest at 1x. This has led me to start testing specifically to that end. The testing consists of a display of vital-sized targets between 10 and 25 yards away that are engaged from a variety of positions as quickly as possible. The targets are audibly reactive, making hit identification easy. It is not unlike some stages of three gun competitions except that, being as cheap as I am, I use an air-soft rifle. The air-soft also allows for targets that move since having someone downrange poses no safety hazard beyond welts. This course of fire was run though by several individuals of varying abilities in order to get as diverse a set of opinions as possible. In the future, I will be writing a composite article with generalized recommendations and guidelines for picking close quarters optics, but for now I will be focusing specifically on the M-223.

You might suspect that the lack of illumination in the M-223 slowed it down in the CQB testing, and this would be true if I had done the testing in low light. However, in full natural illumination very few of the scopes I have tested have illumination systems substantial enough to be useful. Most are run absent illumination and therefore the Nikon did not suffer a disadvantage. This is not to say that the M-223 performed: it was one of the slower optics tested and generally not well liked by the individuals doing the testing. The primary problem is the reticle, which is bulky and gives the shooter the sensation of firing at the enemy from behind a thicket. In addition to this, some minor barrel distortion is noticeable at 1x. This was less severe than in the VX-6 tested earlier. In the M-223, the distortion seemed more to annoy the reviewers than to impede the ability of images captured by the users' off eye to synchronize with the eye behind the optic. I wonder though if eye strain would become problematic with extended use. All told, the M-223 was not a favorite for close quarters use in good lighting and would obviously be of little to no use in poor lighting.

The effect of barrel distortion on parallel lines:



Summary: The M-223 is a quality piece of glass with features chosen by a marketing department living in a city that doesn't allow you to own guns anyway. Ok, I don't really know that, but it might as well be true. The mechanics and optics are spot on, really solid. The features, though, are almost totally unattractive to me. While the performance in testing combined with my trust of and history with Nikon have convinced me that other scopes in Nikons lineup might be interesting depending on the application, I do not see this one as fitting the AR bill.



For those of you looking for the simple pro and con list, here you go:

Pros:
Optical clarity is excellent; above par at this price point
Handling of stray light is excellent
Generous exit pupil
Adjustments are accurate, independent, and repeatable
Adjustments have excellent feel and a zero indicator that resets easily and accurately
Lightweight
Excellent warranty from a longstanding industry leader

Cons:
No illumination
Reticle is not even a duplex. It fails to be precise at long ranges because of a large dot in the center portion
Adjustments are large, their features unnecessary given the limitations on their functionality imposed by the reticle design.
Slow at close quarters because of reticle design and slight barrel distortion
No significant ranging capability
Power change ring is a bit small and slippery

Review of Firefield 1-6x24mm front focal plane rifle scope with rings.

By Les (Jim) Fischer of opticsthoughts.com (BigJimFish on AR15.com and SnipersHide)
July 14, 2012

The Firefield 1-6x24 mounted to my 16" AR:



This little Firefield was one of my highlights at Shot this year and that was before they dropped the price from $215 to $180. At Shot it looked good for the $215 price. Now it looks even better at $180.

Keeping this in mind, I was quite pleased when one of the Sellmark media coordinators sent me an e-mail telling me that not only was one available for review, but that it was, in fact, already in route. I will admit that this is a very pleasant aspect of reviewing low cost optics. Often, with high-priced glass, scopes are sent around the country from reviewer to reviewer and the logistics of this can be difficult since your goal is usually to have several scopes of similar price range in your possession at one time to do germane comparisons. With less expensive stuff, they just send you one when you are ready and you can typically keep it for a good while as well. It is not hard to line things up under those conditions.

Of course, selection of low cost optics to review is trickier: there are a lot to choose from, but most of them are not worth having, let alone buying. I do not care to spend my time and energy reviewing scopes that I know, having seen them at Shot, I will hate. If you ever wondered why most of my latest reviews have been, on balance, positive; it is because I picked stuff I liked to start with. If you want an old-fashioned Simon Cowell beatdown, you can check out the Shot show reports: there are no shortage of optics I dislike.

Getting back on point. I used a smaller lineup of scopes for this review than I have in the past. I did not think it was particularly useful to the reader to trot out a bunch of $1k + scopes and compare them to one that sells for less than $200. The one exception to this is that Japanese GRSC 1-6x which I left in because it is the only other 1-6x I have. Therefore, the lineup of scopes that will be participating in this review is:

Nikon M-223 1-4x
GRSC Korean-made 1-4x
GRSC Japanese-made 1-6x
Firefield 1-6x24

-Summary and conclusion

Background:

Sellmark is the distribution company for the Firefield brand as well as Yukon, Pulsar, and Sight Mark. At Shot, the Sellmark booth displayed all these brands at the same booth probably because, from the standpoint of an FFL dealer, all are the same in that they are purchased from Sellmark. Sellmark does not seem to differ from this point of view in that there is a great deal of overlap in price point, presumed manufacturer, and even product line between the brands. For that reason, my comments on this scope are not really transferable to any other Sellmark-branded product. For the record, I think that LIS optics out of China is the maker of the Firefield 1-6x24 as well as many of their other products.

Physical Description:

The Firefield comes with quite a few extras in the box. In addition to the scope you get a cleaning cloth, flip caps, rings, and a piece of paper with a few tech specs that calls itself a warranty card, but seems to be more of a stand in for a manual. Interestingly, it does not tell you not to shoot yourself or others. This is unusual since the sole purpose of most manuals these days seems to be to convey that rather obvious and therefore unnecessary information. Unfortunately, in my case, the rear scope cap seems to have split at some point in transit. This can be observed in the below image. Despite this split, it seems to be hanging on okay, though I am not sure if it will loosen up over time. The cause of this split appears to be that the rear cap was one size too small to start with: the front one is not nearly so stretched. Hopefully somebody at Sellmark will notice this sizing problem and order the next batch of rear scope caps the correct size.

As with the example I saw at Shot, the machining on the Firefield I was sent looks very good. I feared the example at Shot could have been a one-off CNC-machined prototype. This does not seem to be the case as the production version looks excellent. Often, on inexpensive scopes, a very thick and textured paint has been applied to obscure poor machining. That does not seem to be the case here. The machining looks very good and the appearance of the paint is more reminiscent of mid-range Japanese scopes than anything else. As for the tactile first impressions, the magnification ring moves smoothly and with proper force, though the diopter moves a bit too easily. All in all, the scope looks better and comes with better accessories than you would expect for the price.

Firefield 1-6x24 with box and all accessories:


Rings:

I believe that it is a great virtue for an inexpensive scope to come with rings. This is especially true for scopes targeted at the AR market where you can be pretty sure they will be mounted to a 1913 rail. The simple fact is that including a set of extruded rings probably costs the maker a grand total of $5.00 but if you had to buy a mount yourself it would run you at least $50.00 for the same level system. All that extra packaging, advertising, tariffs, and shipping add up.

It should go without saying that the rings included with this Firefield are nothing like a Larue product. They are extruded, not CNC-machined, and they do not have inserts for the screws. That being said, they seem well-designed to achieve low cost while not failing. The aluminum is inexpensive, very soft, and therefore stretches a good deal as you tighten down the ring tops (I used 18 in/lbs.) However, they seem to be designed to accommodate this deformation as, under load, I observed just the right amount of space between the ring halves. Perhaps this plasticity also serves to somewhat mitigate the negative effects of rings that are not exactly round as extruded rings will never be all that close. The base of the rings are also well-designed. They use a big hex nut and cross bolt to tighten them to the rail. The cross bolt also serves to engage the rail slots and prevent sliding. I torqued the cross bolts to 30 in/lbs without failure. I would not suggest trying the 60 in/lbs some cross bolts suggest. I think the 30 is fine and at 60, I expect they would fail as the cross bolt is clearly not hardened. It is of note that the center line of the scope, when mounted in these rings, will be 1.12" above the top of the rail and not the more common 1.5". This fit me, but I have a very short distance between my cheek bone and my eye. I expect some long-faced British types might have a problem. All details aside, it is my judgment that I do not think these rings will fail under normal conditions and provided the user is careful during installation. That is really probably all you can look for from rings you paid practically nothing for, though I do wish they would have made the center line a little higher to accommodate a wider swath of shooters.

Reticle description, close quarters performance, explanation, and ranging:

Firefield reticle at 1x and 6x:



A few days ago a reader mentioned to me that he looked forward to reading my take on this Firefield reticle. Either he meant that or that he was dreading reading about it. Sarcasm is very hard to pick out in text. In either case, the subtext of the comment was that he was quite sure he was going to hear a great deal about the reticle from me. I found all of this encouraging as it means that I am unambiguously transmitting my message that reticles are not an afterthought, but rather one of the most important of all elements in scope design. Ranging, close quarters performance, and precision can be enhanced or ruined by reticle design choices.

The reticle in the Firefield is quite a familiar one. Not only is it a mil hash style reticle, but it is almost a dead ringer for the reticle in the S&B Short Dot. It differs slightly by not having the marks at .5 mil increments and by skeletonizing the 12 o'clock post, but the general idea is there and the style is unmistakable. Just as on the Short Dot, this reticle is wispy thin at 1x, features five mils of hashes in each direction, and skeletonizes the thick portions of the duplex. The most important difference between the two is the lack of daytime bright flash dot illumination in the Firefield. That does not turn out to be the huge failure I would have thought it to be back before I started CQB testing, though it is certainly not as effective as having the dot. It turns out that by copying S&B you get some of their advantages, even if you can't hang with them in illumination technology.

The most important of these advantages is the CQB performance. While originally I thought that bulky is fast because you need to see the reticle, the more I have tested the more I have come to the opposite opinion. Seeing the target clearly is more important than seeing the reticle. I think this is partially because, due to the design of refracting scopes, the primary aim point is always in the middle of the field of view anyway. I think it is also because that aim point does not move around relative to the field of view whereas the target sure does. The target is just a great deal harder to get a fix on than the reticle. While it would certainly not be ideal to have a scope with a reticle so light that you can't really pick it up, it seems to be much easier to error in the other direction. S&B probably figured this out ten or so years ago when they designed the Short Dot, though they never wrote an article to enlighten us about it. They probably should have since folks always complain about how light the reticle is and it is certainly not intuitively obvious that that is an advantage. The reasonably light skeletonized mil hash duplex in the Firefield combined with a nice flat field of view at 1x and an acceptable eyebox to yield a scope that performs in the top third for CQB speed: pretty good for a scope that is the least expensive I have ever tested.

All is not totally rosy with the Firefield reticle, though. Crank it up to 6x and you will notice a few things for which a little explanation is helpful. You will notice that the reticle lines look sort of like long fat hairy caterpillars. A little explanation of the glass etching process is in order here. Reticles are not etched by mechanical abrasion, but rather with acid. When etching with acid, a mask is first made with material removed in the places which are to correspond to the reticle. This mask is then applied to the glass and acid is allowed to eat the glass where the mask has been cut away. After washing the acid away, Titanium dioxide (also used as white pigment in paint) is applied to the etching and the whole thing buffed out. How fine a reticle can be is therefore limited by some combination of how small and precise the mask can be made, the characteristics of the glass / acid interaction, and, lastly, the yield percentage of good reticles you are willing to tolerate because the whole affair, like the process of manufacturing semiconductors, is subject to a great deal of unevenness. In a front focal plane scope, all of these limitations and interactions are literally magnified because the reticle is magnified as the power is dialed up. In a 1-6x scope the reticle, inconsistencies and all, will be magnified 6x. In a 1-8x it will be magnified 8x. Since acid eats in an uneven manner and tiny masks are hard to make, it is not hard to see how difficulties can arise. For these reasons, the reticle in the Firefield is thick, around 1.2moa, and has an appearance somewhat akin to a line drawn with a Sharpie that has bled a little. I have seen shades of this problem not just on this $180 scope, but also on ~$3000 March ffp scopes which have an 8x erector ratio. It is simply not easy to make reticles in high magnification ratio ffp scopes. All that being said, it is still difficult for a shooter to be precise with an optic that has a line thickness of 1.2moa.

The last thing to talk about concerning the reticle is its ranging capability. I was quite pleased to find, in my testing, that the mil sub-tensions in this reticle are the correct size. While this might seem basic and universal, many scopes have reticles that are not the size they purport to be. This one is sized correctly; a very helpful feature for ranging accurately. In the case of the Firefield, ranging, bullet drop, and windage hold will all be performed using the mil scale on the reticle. This is because, as you will learn later in this review, the adjustments are not 1/2moa as they claim to be. This is not an ideal situation in a mil type scope. Ranging with a mil scope always concedes speed at the outset because it requires calculation. What it lacks in brevity it seeks to make up in accuracy. Part of that accuracy is contingent on being able to dial the drop after finding the range. Holding over for drop is less accurate and it is easy for the shooter to get lost in all the similar looking dashes. This is especially true if multiple targets in the same area are to be engaged or if multiple shots are to be fired at the same target. Recoil between each shot can lead to you holding on the wrong dash. Since windage is usually held not dialed, it is also a disadvantage to be holding both windage and drop simultaneously since your aim point will be somewhere out where the scope has no markings and you will have to try to estimate your place from the markings to the side and above. Nitpicking aside, at the price range this Firefield retails at most scopes don't have any type of ranging reticle anyway, so I think, faults and all, it is ahead of the game.

Comparative Optical Evaluation:

The optics of the Firefield 1-6x24 are much like its physical appearance in that they are better than you would expect at their price point. I would like to point out a few challenging aspects of this scope's design before I discuss its performance. It is very short compared to almost any other scope in my table, 1-6x as opposed to the more common 1-4x, and front focal plane. All of these factors compound the difficulty of scope design. Despite these factors, the Firefield performed well.

More specifically, the resolution of the Firefield was better than the Korean GRSC, though less impressive than the Nikon. Its field of view is virtually identical to the Nikon. This is a middle-of-the-road field of view in general, but when you are one of the least expensive scopes available, being middle-of-the-road is never a bad thing. Chromatic aberration was more challenging for the Firefield. It demonstrates an easily seen green fringing at the interface of light and dark objects in the field of view. This was more dramatic than with other optics tested, though not by a huge amount.

Most difficult for the Firefield was the handling of stray light. This poses a problem for all optics to varying degrees and in varying situations. Bright light positioned at 10 to 20 degrees off of the line of sight of the optic was most problematic for the Firefield. This is a lighting circumstance that most optics find difficult. It can be encountered by shooters facing in the direction of the sun in the morning or evening when the sun is low to the horizon. I was less patient in my testing and simply pointed the scope at the appropriate angle to the sun at the time of day that I was out. that is why there are clouds, sky, and treetops in the demonstration photos below. You will see in these photos that at 1x you can get some greenish light artifacts. At 6x, partial whiteout of the field of view is noted and the reticle gains a frosted appearance. Do not be deceived by the appearance of the 6x photo. The sun is not within the field of view of the scope but rather quite a few degrees outside of it. It is a reflection of the sun off of the inside of the scope that causes that appearance. These photos do a good job of illustrating the extent to which stray light can be a problem to the Firefield in the absolute worst of circumstances. As problematic as that is, it could be much worse. Total whiteouts are not unheard of for some scopes in difficult lighting conditions. Even in the worst situation I could create, the Firefield was still useable.

The extent of stray light handling problems in the Firefield 1-6x24 at different magnifications with the sun positioned 10-20 degrees offset from the point of aim:

Exit Pupil and Eyebox Discussion:

The exit pupil is the size of the disc of light at the point at which it is focused for your eye. Assuming you are using this scope for close quarters work and you are moving about: your head will not be completely stationary regardless of how good your cheek weld is. A larger exit pupil will allow you to keep view of the object through the scope despite your movement, though it is notable that due to parallax error, the reticle will not be exactly where it should be when your head is far off center. People refer to the range through which your eye can move about and still get a good image as the "eyebox". A generous enough exit pupil is therefore a necessary ingredient for a scope to have a comfortable eyebox. The correlation between exit pupil and the perceived forgiveness of the eyebox is not total just as the correlation between a forgiving eyebox and the speed of an optic is not overwhelming. Nevertheless, exit pupil is a necessary component of both these aspects of an optic's performance.

The exit pupil of the Firefield measured out to be quite a bit larger than most. It is not surprising, therefore, that it had a comfortable eyebox in practice. Here are the values I have measured for exit pupils that I have personally tested on various scopes so far, in descending order of 1x exit pupil size:

Nikon M-223 1x, 16.7mm, 4x, 5.3mm
Firefield 1-6x ffp 1x, 16.2mm, 6x, 4.6mm
Viper PST 1x, 16mm 4x, 6.4mm
Razor HD 1x ,13.2mm 4x, 6.5mm
GRSC K 1x, 13.1mm 4x, 6.7mm
GRSCJ 1x, 11.2mm 6x, 4.6mm
Leupold VX-6 1x, 10.7mm, 6x, 4.4mm
Leupold CQ/T 1x, 9mm 3x 4.86mm
Elcan Specter DR 1x, 8.0mm 4x, 7.4mm

Illumination Evaluation:

1x illuminated compilation photo, all scopes set to maximum red illumination:



As you can see from the compilation photo, the Firefield does not have daytime bright illumination. Similarly, you can see that neither did the other scopes that I had as comparisons. They all appear to have unlit reticles. Because of this, I tacked on a couple of images taken for another review of the daytime bright Elcan Specter DR and Leupold VX-6 so that you can see what daytime bright illumination looks like through my camera. Daytime bright illumination is difficult for any conventional scope due to the way in which the illumination is reflected off the reticle. This is particularly difficult if the scope is first focal plane and has a fine reticle like the Firefield. The below photos are though the Firefield at night. Do not be put off by the bizarre distortion or fuzziness of the reticle. The reticle does not actually appear this way, but my camera is incapable of taking photos with so little light to work with.

Firefield 1-6x24 illumination at night, lowest setting:



As can be seen in these photos, the Firefield offers the user a choice of red or green illumination. In either case the whole of the reticle is illuminated rather than a single dot. This allows for ranging in low light. I am not really a fan of this dual scheme since it results in few brightness settings for each color. This is particularly pronounced on the Firefield. While it gets as bright as I expect it could given the limitations of a thin reticle and front focal plane, it doesn't back off much on the lower settings. The lowest setting is probably only half as luminous as the highest and as a consequence, the illumination can be quite overwhelming in truly low light.

Mechanical Testing and Turret Discussion:

I think I will start with the good news. The Firefield owned the power change test. This test is performed by shooting a group at the highest power and then, on an adjacent target, shooting another group at the lowest power. In theory both groups show the same respective aim points. This is especially true for front focal plain scopes. Unlike those of second focal plain, front focal plane scopes should demonstrate no point of aim shift whatsoever. In practice they sometimes do though. As you can see in the scan, the Firefield was perfect. I was surprised and pleased.

Firefield 1-6x24 power change test:



Now for the bad news, those big exposed turrets are mostly decorative. In the box test, the shooter aims at the same place when firing all shots, but moves the adjustments between groups such that a box is formed by the groups fired. This box should be square and the corners (i.e. the groups) should be the correct distance from each other as dictated by the scale of the scopes adjustments. For me, test this means that all of the groups should have the same position relative to the black boxes. They do not. While the box formed rectangular, indicating that the adjustments are functioning independently, and the final group does land on top of the first, indication that the scope returns to zero, the groups do not have the same position relative to the black boxes. The cause of this is that the adjustment magnitudes are not the 1/2 moa they claim. They are also not the same as each other. The windage is significantly less than 1/2 moa and the elevation is more than 1/2 moa. This comes down to a meaning of approximately 1/2 moa for the adjustment magnitude. This is fine for zeroing a scope, but not for using the adjustments to compensate for drop and windage. I feel compelled to note here that neither the scope nor myself is responsible for the obesity of these groups. The latest brick of Fed 719 ammo I have been using is garbage. These were actually the best targets I could come up with. After shooting these with the Firefield, I also strapped on my 14x Zeiss just to be sure that it was not the scope. Things did not improve. Only when I switched ammo did things get better. Bad Federal - no soup for you.

Firefield 1-6x24 box test:



Before we leave the adjustments section, I would like to talk a little about the size, feel, and construction. Usually I do not take apart the adjustment knobs, but the elevation knob was loose on my scope when it arrived. It turned out that it was not the three zero-adjust screws that were loose, but rather a second set of three below. The knob is designed something like a Russian nesting doll. This is perhaps to facilitate the use of different possible knob styles with the some core mechanism. Though the knobs chosen look handsome, I would have preferred them to go with smaller covered ones. This is especially true since the adjustments are not the right magnitude and therefore not fit for use compensating for windage and drop. Zeroing-only adjustments, though not ideal when paired with a mil hash reticle, aren't the end of the world; but I wouldn't parade them around quite so prominently. Lastly, you might want to put an index mark on the saddle so the user will have something to line up the zero mark on the knob with.

Firefield adjustment knob construction:



Some Notes on Durability:

As most of my readers know, I don't do durability testing. The reason for this is cost. The way I figure it, to truly know if a scope will hold zero or not you have to expose it to thousands of cycles of recoil. Unless you have a custom-built machine like the one in Leopold's lab in Beaverton, that would involve a great deal of expensive ammo as well as a lot of wear on a firearm. Given that I do most of my mechanical testing using a .22lr bolt gun to save money, you can guess my opinion on all this cost.

On this scope review, I had an unusual circumstance allowing me to accomplish some recoil resistance testing without incurring unpleasant financial bruises. I was not the only one testing one of these scopes. In a land far, far away; a friend of mine had a second scope that he was playing with... with his full auto. What he found was that after 80 .308 rounds followed and 200 .223 rounds at full auto, his diopter doesn't seem to be working quite right. Now it seems that you can be focused at 6x or 1x, but not both at the same time. I expect this means that one of the locking collars on a lens loosened up, though he also concedes that it is possible that he simply did not notice the diopter problem before. Either way, I think it is probably ultimately a quality control problem rather than a design problem. It just seems to me more like a looseness than a brokenness, so I think is likely that few scopes will be so effected. Either that or Sellmark is crazy, because they are offering a lifetime warranty.

In addition to eschewing recoil testing, I have also refrained from dunking the scopes in water or dragging them behind automobiles. I suspect that you can guess why I don't drag them behind my truck, but I really never had a good reason for the other except that I didn't expect that I would have any failures anyway. That is not really a good reason.

With that in mind I set out to deep six the Firefield, but before I did the deed I thought it might be wise to make sure it was waterproof. The Firefield has a very specific and impressive sounding line in their literature about waterproofing. It says that the Firefield is IPX4 waterproof. That sounds like some special grade of waterproofing. Like maybe it is even resistant to the water that somehow gets through the Goretex in my waterproof boots. That must be special water and perhaps this scope is immune to even such assaults. That is not what IPX4 waterproof means. It has a very specific meaning and that is, "Water splashing against the enclosure from any direction shall have no harmful effect." Perhaps this is a degree of waterproof in the technical sense, but in the common vernacular it is not. In the common vernacular 'waterproof' means IPX7 or 8; immersion proof to varying depths. So, I didn't dunk the scope, but I did learn all about ingress protection ratings.


Summary and Conclusion:

If you were expecting a totally clean bill of health for this scope and are now sitting here disappointed, I am sorry to disappoint you. Furthermore, I am not going to insult you by telling you that your expectations were totally unreasonable. A $180 scope is never going to match up with a $2,000 Elcan. Furthermore, the Elcan didn't get a totally clean bill of health anyway. What you have with this scope is an optic that, for $180, manages to pack in a large 1-6x power range, compact size, and better-than-cost optical performance. It also far exceeds expectations in close quarters use. The only major downside may be durability, but this is somewhat offset by a non-transferable lifetime warranty to the original purchaser. While I am still not totally thrilled with the idea of budget optics, I think this Firefield represents a good value at $180: it looks like its worth twice that.

Here is your Pro and Con Breakdown:

Pros:
Inexpensive
Large 1-6x power range
Compact footprint
Better than cost clarity
Significantly better than cost close quarters speed
Reticle is the correct size and capable of ranging using the mil system
Comes with acceptable rings
Comes with protective flip caps
Lifetime warranty to the original owner

Cons:
Adjustments are not the correct magnitude, exposed and a bit large, and have no index line for the zero
Reticle is too thick at 6x and looks uneven rather than crisp at the edges
The illumination is not daytime bright and also does not have low enough settings for use in very low light
Eyepiece cap is to small and therefore came broken
May have less than ideal QC

Any plans on reviewing the new IOR Valdada 1.5-8 scopes? They have a new offering with .25moa knobs and daytime bright illuminated reticle. FYI. The Pitbull's illumination has also been upgraded to the same brightness.

I do not anticipate any more IOR reviews of any kind in the future with the possible exception of some possible Shot show mini reports. When I spoke to Val at Shot he was not comfortable with the idea of his 1-10x scopes occupying the same line up as 1-8x scopes from other makers as he believed the comparison of an 1-8x with a 1-10x unfair. This was quite the turn off for me as comparisons are always necessarily somewhat imperfect with regards to price or power range or other some other features. It is the responsibility of myself as well as my readers to exercise are judgement in writing and reading comparisons of products that are not totally comparable.

More generally, the distinct sense that I got from Val was that he did not particularly want me to review his products in general. Given that my review of the Pitbull a few years back was pretty negative, I am not surprised by this. It is possible that I may encounter folks in the Central Ohio area in the future with IOR products that will wish me to write up reviews but barring that I don't really expect to again have an IOR product on hand.

Well that is enough of a turnoff that I will not be considering them for future purchases.

So you are right, but by being so, you are also obfuscating the truth.

A couple comments, however:

The military SU-230/PVS-C versions do not have the "aiming circles" in the reticule, and in fact use a slightly different one than the commercial models.

It is the same reticule as the TA01ECOS SU-237/PVS Sight Unit:

http://www.gunshopfinder.com/trijicon/ta31ecos_reticle_diagram.jpg

The only difference is that there is a center dot and no partial illumination like the ACOG version. Per ELCAN, the reticule is "SOCOM specific" and that is why it is not offered on commercial models.

Also - regarding the ARMS mounting levers:

You can, and I have replaced the ARMS levers on both of my SU-230s with ARMS MKII levers which are adjustable for rail width - they are available in a retrofit kit from ARMS for $15 + shipping for a set of two, and are pretty easy to install. You can also have them replace the levers for you if you are uncomfortable hammering rollpins out of your expensive optic.

Yeah, I noticed that in a different post some time back where I had borrowed the same reticule diagram, and went back and changed the linked picture, guess I missed one.

ETA: Went back and edited the post with the diagram from Trijicon's website, hopefully they won't do me like that! But you can go back and look at the original picture by clicking the link above.

Boy am I ever glad that I copied the original Trijicon photo and hosted it on my photo bucket instead of inserting the original post link. I do this to prevent dead photos from occurring when other folks delete things they think are no longer in use. I never considered that there might be more, shall we say disturbing, consequences to posting links to photos that you don't yourself host.

On an entirely separate note, I got my Shot show credentials a few weeks back so I'm getting all geared up for this years Shot blog. In another week or two I should have enough time with the slowing of work to update the table and get some prep work done in order to be as productive as possible at the show.

I have never done hands on testing of any of these three optics and I do not believe any of the reviews, written by others, hosted here included a power change test.

I find this very exciting. I have seen the Vortex and the Leupold in person and was very impressed with both. The glass on the Vortex is very nice and I felt the Leupold was an incredible optic as well. I think the USO has a lot of promise and the Vortex is potentially a best buy in low powered variables right now.

Mr. BigJimFish,

Thanks a ton!

As I've posted in another thread, I have a new SWFA SS 1x4 that I really can't live with the "eye box" as it compares to my older Burris XTR-14. I'm trying to determine if the exit pupil of the SS is supposed to be so much different than the XTR, I can't seem to track down any exit pupil numbers from testing them, just some factory optimal numbers for the XTR. I'd be happy to setup my own test for the samples that I have, but without others to measure I won't know if I have a bad SS or its what I should expect.

Is the test as easy as shining a light down the tube and setting up a vertical surface at the recommended eye relief or find the point where the exit pupil is the largest and then measure that with my calipers?

Thanks again.

Its worth noting not all of those scopes are on equal grounds when it comes to price.


I tried fiddling with the magnification ring as well as the diopter to yield a better two eyes open experience. I was unable to get as good a merging of the images as many of the other scopes in my testing provided. I do not remember if bumping the mag yielded a flatter field of view specifically having magnification in one eye but not the other causes enough problems on its own that flattening things out would not solve anything if that is how it must be done.

Jim - Talking to the custom shop at Leupold...running into the same thing someone else brought up. Other than the multi-gun, doesn't look like (they think) they can do a special order on the VX-6 1x6 or 2x12.

Couple of questions...do you know if they can do the SPR on the 2x12?

Do you have any info on who to talk to that knows more about the 1x6 and the SPR?

Thx


I wrote the Leupold rep concerning these questions. Here is the response:

Right now the custom shop is not doing any special orders on the VX-6’s. Generally speaking there is a 1-2 year wait time on newly introduced products before we are able to offer major customizations due to production demand. The custom shop can currently do external modifications such as engravings and CDS dials, but will not be offering “special builds” until later in the year / early 2013.


The second part of the question: when the Custom Shop does start offering custom builds and modifications on the VX-6 series they should be able to install the FireDot SPR from the 1-6 in the 2-12, but the subtensions will not be correct due to the difference in magnification. Also, due to the design differences between the 6x system of the VX-6 and all other current production scopes, when the Custom Shop is able to do reticle swaps they will only be able to update with the reticles currently available in VX-6’s, or built specifically for VX-6’s. Another question we get is “Can you install Mark 6 reticles in the VX-6?” and the answer is no, because the erector systems are built differently and the Mark 6’s are FFP and the VX-6 is SFP.


If you bought a VX-6 before the "Multi-Gun" model as I did with the ILL Circle Dot you can have it changed. I sent mine in to Leupold and had it changed to the SPR
like in the Mulit-Gun ( for lack of a better reticle from Leupold ) for $159. They did my custom turret for free too.

Try and do a write up on the Vortex 1-6 with the JM1 (?) Jerry Miclulek reticle for 3 Gun! I saw it in Vegas at Handgun Nationals but the red dot looked less bright

I have the Vortex and the dot is definitely bright enough and usable enough as a red dot sight on 1X in the bright TX sun.

However, I'm a big fan of Aimpoints so.......

I can't compare it to the VX-6 as I haven't used one.

U.S. Optics SR-8 BigJimFish Shot Report 1/19/2013.

You may have noticed, as I have, that USO scopes have recently begun to be available through a variety of outlets and in a variety of standard configurations. You may also have noticed that ERGO parallax, which accounted for only 1 in 30 scopes sold, has been discontinued. What the folks at USO realized is that they were suffering a great amount of inefficiency in production for a very few unusual scope orders. What they have decided to do about it is to make a few standard scope models that they will stock for immediate delivery and which will be available though distributors at a lesser cost while keeping the true, full custom stuff available only directly thorough themselves at a higher cost. This will allow most customers a little price break as well as increasing production throughput without leaving those who want unusual features out in the cold. It will also cut down or eliminate wait time for most orders. We’ll see how it pans out over the next year or so, but I expect that it will be a change for the better.

It is also notable that USO has changed the name of virtually every scope they make. SN-3 will no longer refer to any one of eight optical systems. The new names, such as SR-8 for their new short range 1-8x will make a little more sense and only be used one to a chassis.

Speaking of the SR-8, which is what you wanted to know about anyway, a final production version of the daytime bright, red dot illuminated model was shown this year at the show. This is not the only model offered, but rather one of three to be initially rolled out. The SR-8 will be offered in S, C, and M configurations. The SR-8s has conventional, reflected off the reticle and not daytime bright, illumination and will cost $2k. The SR-8c has what amounts to red dot illumination that is daytime bright and runs $2,500, and, if I remember correctly, the SR-8m has both illuminations and runs $2650. In the future there is also a plan for a 34mm SR-8 that will feature an EREK elevation knob.

The SR-8c next to my reference GRSC 1-6x. Sorry for the slightly fuzzy pic.


What I had to play with at the show was the mid priced SR-8c red dot model and it was a great improvement over last year’s early prototype. Most obviously, it has daytime bright red dot illumination. Quite surprisingly, given that last year PR and S&B were showing finished prototypes with this technology, USO is actually the first 1-8x to come to market with this feature, as the Leupold CQBSS is not illuminated in this fashion. I was completely surprised by this as S&B has apparently been so bedeviled by this feature that their scope has been sitting on a shelf mocking them whereas USO just up and did it. Now, to be fair, what S&B has been saying to me is that they just can’t get the dot perfectly lined up in a reasonable amount of time and, on 8x, I did notice that the USO dot was just a tiny bit off. How tiny you ask, well do you notice it in the picture? Didn’t think so. Beyond that, the dot is really for 1x use and being a very tiny bit off at 8x is not a substantial functional problem, though it might annoy you. I have to admit, a little sheepishly, that I did not think that USO would be able to make a dot illuminated 1-8x work. They were dinking around with this dual focal plane stuff that just didn’t seem to make things much brighter and everybody was crying about how expensive the flash dot technology was to do and I thought USO, having never done it before, would not be able to get the job done. Well they did. It’s a dot and its bright.

At 1x with the illumination maxed out:


At 8x with the illumination maxed out:


As for the rest of the scope, I have some cheers and some jeers. We’ll start with the jeers so we can end on a good note. The field of view on the SR-8 is smaller than most at 83.25ft. It is true that other high ratio scopes are generally smaller in field of view than lower ratio scopes, but the Leupold and the March 1-8x scopes are substantially larger than the USO. I also found the USO to be darker than my comparison GRSC 1-6x at 1x. This is not typically the case when comparing high (USO) and mid ranged (GRSC) scopes as both price brackets transmit so much light that one really can’t tell a difference in most lighting conditions. The USO guys assured me that the light transmission is 85% on that optic so perhaps it has something to do with the specific wavelengths in the poorly lit ballroom but it was unquestionably darker in appearance to my eye.

On the good side, the resolution was easily better than my comparison GRSC. I also found the eyebox useable and I think the mini Christmas tree mil reticle offered will appeal to a great any folks who intend long range use. The clicks also felt very good. USO has a smooth but firm feel to their clicks that I find pleasing.

So all in all, a win, and at a price that will keep it competitive even when the S&B, which yes, is better, is released. I’m proud of USO for the quick study on flash dot type lighting.

As Shot show has just ended, and I am tired and will be in transit all of tomorrow. I will handle the March 1-8x, Vortex 1-6x and the Bushnell 1-8.5x in the coming weeks along with quite a lot of other optics that I have seen.

Thanks for reading,
Jim

Bushnell 1-8.5x24mm Elite Tactical Shot Show 2013 report by BigJimFish

Bushnell 1-8.5x24mm Elite Tactical scope:


As you can see from the photo, the Bushnell 1-8.5x24mm is a rather hefty looking affair. It sports a 34mm tube and big, knobby, adjustments. The adjustments do lock and provide 10 mils per rev, so perhaps they at least announce, if not quite justify, their purpose for their size. However, the big tube does not actually sport an objective any bigger than a 30mm tube (actually, it's 3mm smaller than that of the USO 1-8x) and nobody really thinks that a 30mm 1-8x scope would lack elevation range (Bushnell's 30mm 1-6.5x24mm has more than 40 mils). In short, somebody in marketing thought that their new flagship AR scope ought to sport a big beefy 34mm instead of the more svelte 30. If your wondering, it weighs 23oz to the 1-6.5's 18.5oz, so having a big, knobby, tube is not without its costs, regardless of how you feel about size mattering. I can't help but feel that this scope could have made 20oz without loosing a sliver of functionality.

Bushnell 1-8.5x at 8x with no illumination:


Bushnell is quite proud of the brightness of the illumination system in the new 1-8.5x. It does not use the beam splitter tech of the USO or S&B or a fiber system like the Leupold VX-6 or Vortex 1-6x, but it is nevertheless bright. The tech used appears to be of the conventional reflection off of the reticle variety and I am surprised how bright they managed to get it. It glares a bit (you can see the stray illumination in the 1x photo), giving you a feeling that they're pushing the limits like an engine running on nitrous, but I would definitely characterize it as daytime bright. I wonder how long the batteries will last, or, rather, not last. The illumination control is analog and has 9 brightness settings + 2 additional night vision settings. The reticle being illuminated is the same as that in last years 1-6.5x. They call it the BTR-2 and it is a horseshoe with a little mil scale below it.

The clarity of the new 1-8.5x is exactly the same as my GRSC reference scope, though its field of view is better than the GRSC. It's good clarity, though at the $2k price point, I expected the next step up in glass. Adding the extra 2.5x in magnification is nice, very nice, but this is a much higher priced optic. I thought last year that the 1-6.5x should have been less expensive and I am leaning that way on this one as well. $2k is really Shott glass territory with scopes like the USO 1-8x.

As for hands on looking about with this scope, I didn't notice any real problems. The eyebox seemed ok and the adjustments felt fine. I just went away feeling that the optic was designed by a marketing department to fit what they thought it ought to look like. I didn't feel that form followed function, but rather the other way around. That, and I thought it cost too much for a scope that does not have dot illumination or, I suspect, Shott glass.

Thank you Jim, the 1-8.5 was the scope I was anticipating this year. Looks like it missed the mark for me. What was your impression of the Christmas tree reticule in the USO?

Is there a reticle in that 1-8.5 1x image? I could be going crazy but I cant see it.

Me neither. I thought I was going insane. Now I know I have company.

I'm also hugely curious whether BigJimFish managed to get his hands on the Bushnell 1-4x24 Throw Down PCL scope. That looked like a lot of scope for the money, especially if the glass is good. What's the scoop, Jim?
