KILLERB6:
553.A65 (SU-231/PEQ): 6 months Iraq, 3 years Afghanistan on M4/A1. Round count: approx. 10k total. Beaten/hit regularly, "roll bar" gouged but no malfunctions.

553.A65 (different unit than above): 6 months Afghanistan. Approx. 1k rnds. No problems.

552 A65/1: 6 months Afghanistan an M4. Round count: approx. 1k. Current "abuse" pattern is tons of dirt/sand/dust. No malfunctions.

Personal weapons: Moderately severe use of civ equiv. of 552 A65/1 (many years, approx. 10k rnds) and EXPS3 (1 year/1k rnds) with no malfunctions.


Aimless:
I have a Bushnell holosite, the low end version Eotech sold under the Bushnell name. I bought it used around maybe 2004? I haven't used it much. It's on my slug gun. I have used it deer, turkey and rabbit hunting so it does seem to hold up to recoil okay and has been out in the snow and rain. Holds up okay to 3" slugs and 3 1/2" shot rounds. I was surprised recently when I turned it on after not having used it for probably 3 years and it still powered right up.


Postal0311:
Had an Eotech 512 rev F. Was a big fan and highly recommended it.

However I found that it would drain batteries when off. All too often pulled the rifle from the safe and found the batteries were dead. Had batteries leak inside it and caused problems. Eotech replaced the battery box, and I got rid of the sight.
Customer service was very friendly and helpful.



On a sidenote, if you want a good absolute co-witness QD mount, the GG&G lever as shown works great. The Larue riser raised the Eotech too much for my tastes.

Ran it on 16in and 10.5 inch uppers. Had it for about a year in. . . maybe 2007-2008.


Zhukov:
I have owned a 511 rev C and a 512 rev F.

The 511 is a sight I would NOT recommend. The N cell batteries are crap, they don't hold a charge, and the sight itself went back to EOTech for warranty service due to draining the battery too fast - it would kill batteries in the matter of weeks even with the sight turned off. Customer service was excellent, and they even upgraded it to rev D or E (I can't remember) before shipping it back. I subsequently sold the sight as I was tired of the N battery life.

The 512 I bought has been flawless and still has the original AA batteries in it. For several months after I got it, I would measure the voltage of the batteries with a multimeter and did not detect any drop in voltage.

Both sights always held zero and they feel very rugged. The integral mount allows for a perfect cowitness with a BUIS or iron sights. Even with the problems I had with the original 511, I prefer EOTechs due to the reticle design. I find the 65 MOA ring/1 MOA center dot perfect. The 65 MOA outer ring greatly aids in acquiring targets at close range, and the fine resolution of the 1 MOA center dot is great for shooting 200-300 yards. The only thing I dislike is the fact that the brightness always resets to its medium setting, requiring several button pushes to bump it up for shooting in bright daylight. The 1000 hour rated battery life is fine with me - I'm not going into combat and I generally always find some AAs laying around if I need to change batteries once a year.

Greg3:
512 rev.F

It has been on my Colt M16 (appx 20,000 rds of .556)
I then ran it on a Rem870 (appx 300 rds of 3" 00mag)
I gave it a go on my SA M1A (appx 300 rds) until I bought the scope I wanted.
Then on to my AR57 11" upper for a bit (3 50rd mags) Didn't like it on there as not much rail space on the rear of the upper. The new XPS would be perfect for that one.
Now it is at home on my STG556 (appx 3,000rds now)

I bought it many, many years ago and it has been 100% on everything. Never a problem to date.

I love my 512.

1st-Armored-Division:
I own three EOTech HWS optics. They are a model 551/rev F, 552/rev F and a 552XR500.

551- I have had this optic for several years and have used this EOTech more than my other models. I have used this sight on two different Bushmaster ARs with over 3000 rounds fired with this optic mounted. I have also shot several dozen rounds through a Mossberg 12 ga shotgun. I have also fired a few hundred rounds with this one mounted on a AK, caliber 5.45x39mm. This optic is smaller in length compared to my other EOTechs and that would most likely be from the N batteries that it uses. The N batteries are IMO the only problem that I have had with this optic. The N batteries just do not last very long at all even if you are able to get the 200 hrs and these batteries are also not as easy to find. I have to admit that this EOTech 551 HWS has been very dependable and reliable.
552- I have also owned this optic for several years. I have fired over 2000 rds with this mounted on two different Bushmaster AR 15 rifles. I have also shot several hundred rounds through a FNH PS 90, caliber 5.7x28mm with this EOTech. This optic uses the AA batteries and I have consistently received good run time with this holographic weapon sight. I have not had any problems with this EOTech and it has worked very good for every weapon that I have installed it on.

552XR500- I have not used this optic yet as it is still new. I got this EOTech for future use on either my Barrett M107 or my Barrett M82A1-416B for when I switch from Leupold/NightForce scopes to a shorter range optic. The reticle display is very nice on this model also with 30 settings. This optic uses two AA batteries.

In summary, all of the EOTech HWS optics that I own has been excellent. The optics have been very durable and allow a good deal of adjustment for windage and elevation. The display is also a plus for closer targets yet these optics work good for longer range engagements also. The display is very good on my models and they have a good deal of flexibility with intensity of the reticles. The models that I own are also NV compatible and can be switched to this mode with one button. These optics can run programmed for 8 hrs (right/up button) or 4 hrs (left/down button) once you go through the function check upon starting the power, then 4 or 8 hours they automatically power down. One other big benefit of the EOTech HWS optics is that they are combat proven and have helped dust a bunch of insurgents/terrorists during field usage by our Military and I know that many combat infantry badges have been awarded using EOTech Holographic Weapon Sights.

bjwar10:
I've had this 552 for about a year and have had no issues. I got it used on the EE so I have no idea how old it is. Still working on the same battery I put in it when I got it but I plan to replace it like I would a smoke detector battery here at the first of the year. I've got it on a Stag 16" and have about 1000 rounds on it.

Airbrush:
I'm running a 512 with the x3 magnifier which I love.

The one thing to be aware of is if you have an astigmatism which you're not aware of the reticle will have a ghost & be very blurry.

I have this condition, but glasses solve it.

EJThor:
I have a 512 Rev. F on my carbine. About a thousand rounds through it with the Eotech. Zero issues. I love the 1MOA dot and ring setup. Works great at close range, and with a 3X magnifier, it's good for longer distance shooting as well. I installed a set of Lithium batteries in it in March, and they're still good to go. The only downside is size/weight. I might give one of the CR123 ones a shot down the road, as they're much smaller and lighter.

heavyduty:
I have had two and currently own one:

511 Rev F -
Bought new in '04 or '05, whenever "F" revision first came out. Ran for thousands of rounds on my 9mm carbine without an issue not related to the poor life of the N batteries. I did have a set of batteries leak early on, but that wasn't EOTech's fault - and they still repaired the sight for free. (It needed a new battery compartment and gasket, no major damage.) I finally got sick of the N battery limitations and sold it a few months ago. It was a good sight crippled by crappy batteries.


XPS2-0 -
Bought new in 2010. Not a whole lot of runtime on it yet, the economy has really put a cramp in my centerfire shooting activities. Maybe 2000 rounds or so downrange so far including in the rain and snow. No issues at all, and I don't expect any. One thing I wish is that mine was slightly newer - it has the first design molded battery compartment tether which doesn't rotate as smoothly as the current wire tether design.

Blackhalo:
512- Rev F... bought 3 years, 3-4 thousand rounds on different rifles with no problems, still works perfect. Just put it on a Larue riser and I should have done that a while ago, allows for a much better cheek weld for me.

Mccray
I've owned a 516.A65 for over a year it has been mounted on a 5.56, 6.8 and .50 Beowulf. I would estimate it has withstood about 4000 rounds. I have never had any problems with it and am still on the original set of lithium batteries. The field of view and ease of aquiring the reticle has made it a favorite of mine over my AImpoint Comp2 and ACOG for close /medium range targeting. I like the way it cantelevers over the handguard wich allows clearance for an Eotech G23.FTS magnifier and troy folding BUIS. It is a few more ounces than the competition unless you get an XPS model and the battery life could become an issue in a TEOTWAWKI type situation and the reticle can be a bit fuzzy if you don't have perfect eyes. Other that that it's a great optic. I would say the easiest to use overall. An extra plus is the 65MOA ring wich can also be used for range estimation for holdover. Something plain red dot sights cant do.

kotegoshi:
* Model used - 556.A65 (CR123 version with side buttons and NV settings)
* Length of service - Two years
* Firearms used on - 16" AR-15
* Number of rounds - ca. 1400
* Anything else that is pertinent - Co-witness with BUIS is even better than I had expected.
Return to zero (remove and replace unit) is excellent.
Good to excellent battery life.
Reticle is a little blurry (not NV bloom) when used in conjunction with a PVS-14. I think this is due to my focusing the PVS-14 on the target, but could be my bad eyes or just the extra layer of glass. I have not experimented with the combination as much as I had hoped (yet).
BONUS, when sighted in at 100m, the bottom tick mark is virtually dead on at "inside the house" (5-7 yards) range.
* Any problems encountered and customer service experience - None/NA

Evile
EOTech 512.A65/1
3 months original batteries
500 rounds
no issues
just added the EOtech 3x magnifier will report on that soon

YWHIC
I have a 2002 Model 552 w/NV... I just got it off EB for $150..

So far I have shot 220+ rounds from my DPMS 308 16" with 0 issues thus far..

I did clean the contacts and toss out the OLD batteries...

The clicks can't be heard and are barely felt.. I just take my time when adjusting it..

I agree on the middle 12 setting (when u first turn on) as being too dim in bright light.. but I am happy for the $ I paid..

Considering the price point is dropping to sub-$400 (NEW).. they are still worth

Same here,

Except customer service sucked for me. Took weeks to get a replacement battery cover. Loved it but the battery drain was unacceptable.

mks99
512 F rev

3000+ rounds of 9mm out of a Marlin carbine. Blow back with a pretty good recoil to it.
Moved it to a 5.45 carbine and have over 2500 rounds there.

Its all plinking and range stuff so no really hard knocks other than your typical drops and falls.

Bought a second 512 and only have a 1000 through it.

Also picked up an XPS recently. Nothing to report yet.

Never had to send any of them back or any problems. Been using them with a YHM and LaRue risers. I've tried to keep the removal rate of the screw mount as low as possible to keep from wearing it out. The RTZ is perfect with both the integral mount and the LaRue.

Love the 65 mil ring.

2007model 552.A65 - .308 AR ~500rd, somewhat dim compared to newer models. Holds zero well with GG&G lever (on and off several times). Drains alkaline batteries after ~6months. Don't use it much, usually keep the scope on it.

2009model 512.A65 - 30.06 Remington 7400 deer drive gun. ~300rd, no problems even with rough use bouncing around in truck/boat/woods.

2010model 512.A65 - RFB .308, ~1000rd, no problems. Has brighter max setting and longer battery life than older models.

criley
Owned a 512 for one year.
Sits atop of a 5.45 upper.
Attached via a GG&G accucam which is very nice
Several hundred rounds under its belt


Like everything but I do have this one issue - it does drain batteries to some degree. New alkalines did not last a year - perhaps only 6 mos... and they were not used heavily.

epointer
512 have had it for a little over a year still the same batteries as when I purchased it. No issues at all.
552 I have only had it for a couple of months (bought used of EE) but the manufacturer date is 2005. No issues with this unit.

Mounger
I have had a Model 512 for 5 years.

Several thousand rounds on several AR's not problems what so ever. I have found it to be extremely rugged, reliable, and user friendly. I have been running a 3x Mako magnifier behind it for 6 months that has turned out to be a great experience.

Recently loaned it to my brother who is LEO because his was "eating batteries" and was not operable when he really needed it. I knew mine was good and he needed it more than I.

I took his Model 512 (also 5 years old) with the intent of sending it off for repairs. I put a known good set of batteries in it and it did not work at all! Upon further inspection I noticed that one of the battery terminals on the closest to the lens side was very corroded. I scraped tons of corrosion off of it, put the batteries back in and it fired right up! Hmmmm? I then put the set of batteries back in it that were supposedly eaten and it again fired right up!

I imagine a set of batteries early in its life leaked starting the corrosion. I theorize that when it stopped working and he assumed it was dead batteries the act of replacing the batteries would scrape enough corrosion off for it to work. This corrosion would promptly set up again and break the connection, making him believe that the batteries were drained.

Since I cleaned it real good I have left it on for 3 days continuous and it is still going strong. He reported that is would "eat the batteries" in a week turned off, so I think I have it. I am going to experiment with it some more before I give it back to him. I will get back with yall if it turns out I'm wrong.

Tommytwoguns
I have a 512 RevF. After about 1500 rounds with it I took a carbine class. During the class the reticle was very dim. New batteries didn't fix it. I used it okay during the class, but contacted EOtech afterwards. They said it was an issue and to send them the optic. 1.5 weeks later I got the sight back with no issues. Apparently, some layer in the holo sight de-laminated.

I haven't had any major issues with the optic other than that. The optic was still serviceable during the class, so I can't really complain since they fixed it quickly and for free. Good customer service.

MaineAR
I've had my EoTech 512 for about 4 years now and it has been a fantastic site. I've had it on several rifles with a GG&G quick disconnect mount. I've never had an issue with it and would buy another in the future.

Friendly_Crusader
511 made in 2001

personally used for 2 years, 2500rds +

no problems, not even battery drain problems, but it does feature a short battery life.

fuzzy03cls
I have 2 512's plus a Bushnell holosite that's like the 512 & takes AA batteries.
1 512 is 2006, on AR15
1 512 is 2010, on AR15
Bushnell holosite 512 is on my AK47
Round counts are upwards of 3K for each.
All 3 sights have worked great for me. I have no battery drain problems, or recoil issues with the batteries. I have dropped or banged my AR a few times, the sights have held up well. Zero holds fine.
All 3 sights last easily 6 months on lithium batteries.

I have owned a 511 & the Bushnell holosite equivalent. Performance was the same but the batteries did only last about a month. Even when off.

I played with the newer XPS sights. I just don't like the size/feel of them & the batteries. I prefer AA batteries cause I can find them anywhere.

Steve_in_PA
512 user for 3 years. Replace the lithium batteries once a year. No complaints or issues. Rifle is a Bushmaster. Several thousand rounds put down range; general plinking, load developement, LEO qualifications, LEO training and instructor schools, etc.

GIDDS-45
Just purchased an EOTech EXPS-2-2 (OPMOD)......got it yesterday. Fired it up and was not impressed with the reticle......All I can say is it was fuzzy. Not a clean, concise circle, crossbar or dots. Seems like the particles of light were scattered especially at the 10 and 4 o'clock areas of the circle.Another way to describe it is it was like a reticle on a standard scope that was extremely out of focus.

Called and they said send it back....which I have....for a replacement.....Are my expectations too high for what the reticle should look like.....

Can someone else tell me how sharp the reticle should be?

edp3
The dot and circle on my eotech are crisp. Maybe this is your problem.... From the eotech website: If you wear corrective lenses for nearsightedness, you will require them to see the reticle in focus as it is projected onto the target plane. If you wear bifocals or have astigmatism, you may see a distorted reticle.

I have an Eotech 552.A65 Rev F for about a year with around 2000 trouble free rounds.
Mounted on dpms frankengun and a s&w mp15.

Tommytwoguns
Turn down the brightness. It doesn't need to be on 36 unless it is really bright out. If you have the reticle turned up to high it will definitely look fuzzy!!

I assume this if your first EOtech, if I am wrong and you didn't have it too bright, please disregard my post.

Zhukov
Take a picture of the reticle. If the reticle is sharp, it's your vision. I was in a similar position and was ready to send it back. When I took a picture to show them how bad it is, I was stunned to notice that the reticle was sharp.

Don't forget the usual tips to avoid reticle bloom:
1) Focus on the TARGET, not the reticle.
2) Keep the brightness turned down when the ambient light drops.
3) Fuzziness is exacerbated at night.

EJThor
As everyone else has said, it's more than likely an astigmatism. I have a pretty bad astigmatism, and without my glasses on, the reticule looks like it was cut from red felt by a two year old on crack.

Burnsy87
Okay, I can't find anything about this online.

What is the difference between the EXPS 3-0 and the EXPS 3-2? I don't see any differences in the descriptions.

Okay, looking again, what the hell is different about the XPS 3-0?

Zhukov
The -0/1/2 are reticle choices.

-0 is the standard 65MOA outer ring with 1 MOA center dot.
-1 is a single 1 MOA center dot
-2 is like the -0 except that it has two 2 MOA aiming dots (1 centered, 1 for a BDC distance - can't remember which)

I believe the EXPS has side buttons and a QD base over the XPS.

[ETA] The difference between the XPS2 and XPS3 is that the XPS3 has the NV-compatible setting.

SpringerXD9SC
I was trying to find information on this but could not find anything. I was wondering if EOTech has changed the body of the 512 for the 2010 or 2011 models? what i am talking about is under the batter compartment in front of the protective hood (hope you guys can figure out what i am trying to explain). Did EOTech almost cut that part out to clear the delta ring / barrel nut?

RDTCU
Yes, they did.

I've got both versions, and the newer ones will clear standard-type handguards, including MOEs

kw918
I bought my EOTECH MPO system, which is the ar556 with the 65 moa and the vertical 1 moa dots for using the 3x side flip scope. I have had no problems with mine. Even with out using my glasses, I can engage close targets by putting the 65 ring on the center of mass. with the scope inline the 1 moa dots are clearly visible and can be used. The ring outline gets fuzzy at max brightness, but I believe it is from the type of laser being used, you will see the same bloom and sparkles with a gallium arsenide diode laser such as a pointer. I will use only eotech products for CQB applications and medium range unless I need a " true "scope. No more aimpoint for me.

545x39
I had an EOTech 553.A65/1that I used on a S&W M&P15R (their 5.45x39 AR). I used it for about 500 rounds before trading it for a different optic. I never had to change the batteries from the ones that were in it when I got it. (I bought it used from someone else.) My only complaint was the ARMS throw levers didn't seem to hold it tight enough. With the levers closed I could still move the EOTech back and forth in the rail slots. I didn't have the manual so it's possible that I could have adjusted how tight the levers got and not known about it, but I did try to figure out a way and couldn't. Other than that I liked the EOTech a lot and may get a different model in the future.

Model used 517
Length of service About 12 months
Firearms used on Ruger SR556
Number of rounds Around 600
Anything else that is pertinent The original batteries lasted me almost the whole year. I did turn it off when it was stored in my house.
Any problems encountered and customer service experience While in a competition, i started on a shaded side, while moving along i went to a place where the sun was over myself and the target, there was a blur moment when i got on target. The eotech reticle appear to slowly move to the center of the glass and it took me a second to fire that section of the course. Only happen once.

Hello new to the forum. Hoping to get any info about the eotech 553 with a.r.m.s quick detach mount.
Recently bought a used one. works great, some of my ar15s ive tried mounting it on, the sight was a lil loose on the rail.
Question: Is there any way to adjust the tension on the a.r.m.s mounts? Looked on yahoo and google and too many sale offers.
Any info would be appreciated thanks.

Im wanting to get a EOTECH EXPS or XPS for my AR, my question is when the battery change is needed do you have to pull the sight completely off to change batteries or can you change out batteries with it still mounted? Ive also looked at the 512 and 517 but I think I like the size of the shorter EXPS and XPS models....Are there any more upgrades on these models compared to the bigger 512-517 models ? I know the smaller models use a cr123 battery compared to the bigger AA batteries.......any thing you guys can reccomend ? ANY Do's and Do Not's ? Thanks......

Can't speak to the EXPS but on my XPS2-2 the battery is easy to change. Just unscrew the cap, sight stays on weapon.

I'm convinced on the EOtech, but I have questions about zeroing, cowitness, and being able to have a BUIS and the G33FTS magnifier at the same time.

(1) Do the optics come out of the box mounting/cowitnessing lower, higher, or the same as the CompM4 I'm issued?
(2) If not the same, how does this affect zeroing?
(3) If not the same, what riser would make it the same?
(4) Will the G33FTS fit over the matech BUIS? what about with the included 7mm riser? Are there BUIS that fit under it with or without the riser?
(5) What mount would put the EXPS or 512 at the same height as the magnifier on the riser?

I'm a pretty simple minded (but thorough and thoughtful) kind of grunt. If the answer is that the optic is (out of the box) the same height as my issued CCO, and the magnifier will fit over a matech out of the box without the riser, a simple "Roger, you're good to go" is sufficient.

Your experience and input is much appreciated.

I'd like to get an XPS2 along with a magnifier. Is is hard to turn/off, adjust brightness settings due to the placement of the buttons on the rear of the sight with a mag mounted? In other words, does the mag get in the way?

(1) Do the optics come out of the box mounting/cowitnessing lower, higher, or the same as the CompM4 I'm issued? Your CompM4 is probably absolute co-witness. The 553 and EXPS (maybe others) are 1/3 lower co-witness (the sight sits a little higher) but older models are absolute co-witness.

(2) If not the same, how does this affect zeroing? Zeroing isn't affected at all.

(3) If not the same, what riser would make it the same? You will only need a riser if you get an absolute co-witness model and want 1/3 lower co-witness.

(4) Will the G33FTS fit over the matech BUIS? what about with the included 7mm riser? Are there BUIS that fit under it with or without the riser? It looks like it will judging by this pic:



(5) What mount would put the EXPS or 512 at the same height as the magnifier on the riser? The magnifier comes with a riser so it is compatible with either absolute or 1/3 lower co-witness.

I'm a pretty simple minded (but thorough and thoughtful) kind of grunt. If the answer is that the optic is (out of the box) the same height as my issued CCO, and the magnifier will fit over a matech out of the box without the riser, a simple "Roger, you're good to go" is sufficient.

I am new here, and I apologize if this has been asked or answered. I looked around but did not see it, so I'll throw it up.

I am currently debating between the following, and am trying to figure out which to get. I do not require nightvision, but am interested in adding a magnified at some point in the future. It is my SHTF Rifle as I already have multiple pistols in the apartment for home defense. My weapon sight experience is primarily with iron sights, the CCO from the Army, and the ACOG. I love the ACOG and wanted to get one, but cannot justify dropping the cash on one right now, so I opted to go with the EO Tech as I was never a fan of the CCO.

1) EO Tech 517.A65
- Originally looking at this one because of price point, common battery, and the side buttons

2) XPS2-0
- Looked at this because of the size, but unsure of the battery life and the battery itself. Not sure how I feel about the rear mounted buttons

3) EXPS2
- Same reasons as the XPS2-0 but it has the side mounted buttons

With the XPS and EXPS I will have to wait until March because of the back log, but if they are the better way to go, then that's what I am willing to do. I am trying to avoid the EXPS because of the price point, but am leaving all options on the table. Any help is greatly appreciated.

Typed this out for another thread, and figured I may as well re-post it here for others who may be interested:

To recap - I own an EOTech 552.A65 Rev. F, and two EOTech 553.A65TAN SU-231/PEQs. The 552 has been owned since 2007, and while I have had one 553 since 2010, and another since 2011. The 552 I bought used from after having been used previously in Iraq (it was a great deal! ), and one of the 553s was used in Afghanistan.

EOTechs tend to be a polarizing issue on many "gun" forums, and I have little interest in getting into an EOTech versus Aimpoint debate, however, I must interject:

To imply that US SOF is somehow saddled with the EOTech against their will "because that's what the government bought them" is patently false. Evidence to this effect has not only been tendered by recent and operational members of those communities, but also the fact that while the Aimpoint was standard issue, many end-users elected to personally purchase their own EOTechs and even Bushnell Holosights, while many units chose to purchase them using unit funds, the direct consequence being the eventual adoption of EOTechs over Aimpoints as the "official" USSOCOM issue optic. Furthermore, particularly with regards to USASOC - the Aimpoint CompM4 and M4S already exist in huge numbers within the Army supply system as the M68CCO, and it would be less than overwhelming for USASOC to arrange to be equipped with reflex sights under their "home" component and use Aimpoints if they so desired.

In addition, the implication that US SOF simply tears through EOTechs without concern for longevity "because they can just buy new ones," as if they're running one operation, then trading their optic in for a NIB unit is also not supported by any evidence. In fact, the EOTech 551.A65, a model that has been discontinued for several years, the "tragically flawed N-cell EOTech" is still in relatively wide service with some of the best equipped units within the establishment - the kind that can afford $40,000 NVDs. If EOTech service life were in fact so atrociously short - the discontinued 551 should have faded from service long ago, as should the 552s, also quite common.

The idea of using an EOTech without iron sights of any kind is not an unusual one. It's just... not. By people who have a much more realistic expectation of needing to use an optic equipped weapon in their own self defense, or even in offensive operations than the vast majority of people here. If the EOTech were so unreliable to the point of continually needing BUIS, the leaders in the various organizations that use EOTechs would be cracking heads and bringing down unholy hell on anyone caught without BUIS. Particularly in small unit tactics - if there was so much risk associated with the use of EOTechs - it would be an unacceptable risk to allow even one person to go into action without BUIS, as it would endanger the entire unit if even one weapon became NMC (non-mission capable - unable to be accurately aimed). Nor would their peers allow this either.

They do, however, get free, and nearly unlimited batteries.

I have my own personal experiences as well to draw upon, some of which is organizational, in favor of the use of the EOTech.

I have personally owned four Aimpoints and three EOTechs in my life. I currently do not own a single Aimpoint, and fully intend to purchase more EOTechs when it becomes realistic for me to do so. I have used, and had come through my responsibility literally hundreds of Aimpoints, but still prefer the EOTech.

A couple other comments:

- I'm not an electrical engineer, so I can't comment on why this is so - but EOTechs, from what I can tell - don't like being neglected. They don't like being left alone for weeks or months at a time, only to be turned on at intervals. Almost every EOTech problem that I have heard of has involved an EOTech that was in some form of storage for significant periods of its service life, rather than being in continual use.

- For whatever reason the above is true - it may be that EOTechs, by a combination of battery life, for reasons already mentioned (laser pattern emitter versus LED diode) and aversion to neglect - they may not be the best option for a casual civilian shooter with a day job for home defense, or even an LEO who stores their weapon in a rack 99% of the time, only to deploy during emergencies and/or the occasional warrant service or SWAT "op."

As with any other equipment choices - you need to understand what you're getting, its advantages and limitations, and above all, be realistic about your needs and ability to maximize the advantages while mitigating the disadvantages.

Regardless of personal ego and conceits - it is a simple fact that the needs of a service member that is forward deployed do not always correspond with the needs of an armed citizen or LEO. You need to choose your equipment based on your actual mission profile, whether its home defense or civil order or kinetic or full-spectrum military operations, and understand what it is that you are training for, if at all. Some people just want to look cool and plink at the range.

I have an Eotech 512, don't know the revision. So far it's been great, on the first set of batteries I installed (Energizer AA, I don't trust Duracell any longer). I turn it off when not in use. It was purchased two years ago (late 2011)

My question is maybe not optics related. I recently bought a Primary Arms 3x magnifier. I can't fit both on the rail of a Colt flat-top since the handguard interferes with the bottom of the Eotech. I pulled the handguards and installed the magnifier and Eotech together and like the combination. So, are there any sort-of-stock handguards I can use or should I take a Dremel to the top of the Colt handguards? (this actually sounds like a way to end up with a cracked handguard so I don't really plan to do it).

What worked for you?

I don't want to get into a free-float handguard at this point; maybe in the future I will.

551, had about 2 years on a rifle and about 4k rounds. Started draining the batteries in a matter of days, sent in for warranty service and got it back in a week and a half. Sold it an the rifle not long after.

Bought a 553.A65 black SU231/PEQ Feb of this year, reticle started getting dim in daylight(suspected nitrogen leak) then the battery springs fell out after about 4 months and 1500 rounds. Sent it in, door-to-door in less than a week. Looking at the shipping info, they got it fixed and back in the mail on the same day.

what if I pulled the batteries out, and only put them in when I needed the rds (it will be in storage). would that solve those problems?

So far a very useful thread to me. I know little of EO Techs many models, Is there one that uses AA batteries and can easily swithch, Point of aim wise from a flatop AR-15 to a Flattop AR-10. My AR 10 only has a 16 inch barrel, but I would expect to use it at longer ranges than the AR-15. I am just punching paper and tin cans, but I would like to be consitan shooting. If this seem a bad idea say so and I'll use my iron sights on the AR10. I have no sights, now, on the AR15 I am building. It will get shot a lot more than the AR10.
