I have decked out an AR mostly focused on accuruacy, however, it is in a carbine size configuration, I comprised and got a 18" barrel made(krieger). I plan on using it for home protection, blowin shit up, but I also wanted to be able to drill holes at 200 yards+. A lot of money went into this weapon... I originally wanted an ACOG TA31A with triangle reticle. According to some posts I have read, this optic is great for CQB quick target aquistion, glowing reticle, etc. However, will I be able to drill holes long range at all with this optic or is the magnification simply too low. Also is the reticle suitable for long range? I was thinking with the triangle reticle I could sight it in so that @ 200 yards the top of the triangle is where the bullet goes. That way it would still be quick target aquistion at close range and still be suitably accurate and also be able to get good groupings @ semi-longrange? If it simply will not work for any distance, what is a good alternative? Something in the ACOG price range or less that I can drill holes with, but still use for home defense? I appreciate your advice! |
The key to shooting accurately with the ACOG is having a precise sight picture for the range the target is at. Most people zero the top of the reticle (top of donut or tip of chevron/triange) at 100 yards, so that the BDC is close. If this is the case, then all you need to do is figure out the sight pictures required - ie, the target / reticle alignment - for however small targets you want to hit. My personal limit for guaranteed hits on golf ball sized things with the TA11 is about 125 yards. -z |
hahahahahahaha!
...and washers and dryers and old refrigerators and microwaves and computer monitors and water softners and heaters and fireworks shells and tannerite and camp fuel bottles with flares taped to them and...stuff with fire and loud noises and more fire... Yeah, I think I could be part of the club.

Appliance shoots! Great fun. Also trailer trashin'. Last big trailer shoot we attended they were towing old 40-ft trailers (like the portable trailers used for temporary classrooms), onto the range at 3-500 yards and seeding them with hidden explosive charges and cans of gasoline. Seeing one of these literally explode with your wife on the trigger of your favorite AR - priceless. |

I have the TA31A, and I like the triangle reticule. Personally I prefer a fine aiming point that won't obscure the target. I have had issues in the past with donut or large dot aiming systems when fine aiming is required. The triangle avoids this somewhat by allowing you to use its top for fine aiming. Either one would be probably be a good enough choice for most of us though, obviously the TA31F is liked by its owners as well. |
In short, unless quarters are so tight as to necessitate the temporary tranistion to a HG, an HG is ALWAYS a poor choice if a long gun is available. MatKat - may also want to look at a US Optics SN-4 Good luck |

Honestly I like the my TA31 with the "Donut of death". I think that if you cover up your target with a triangle then you are obscuring what you are shooting at. I like the TA31 because you can see through the donut and see your target completely. If you can see it you can hit it. As for pinpoint accuracy, to me the ACOG is a "see it hit it" kind of optic, it is not one for a tack driver. Keep that in mind when trying to match something up to your uber accurate Krieger Barrel.

1. SN4 Not comaparabel in price... its more expensive 2. SN4 is TRIPLE the weight of a TA31 4. SN4 has low battery life UNDER 12 HOURS 5. SN4 requires additional riser to fit on AR 6. SN4 is HUGE |

i have the ta31 and it is very accurate if i want it to be or if i am. i agree with whoever said to get the ta31f that would be more of a precision scope than the others in my opinion. i plan on getting a ta31f for my precision rifle when funds permit. but the donut has that it is capable of being a tack driving scope |
USO is not as well known or utilized for a variety of reasons however they do offer some great products. An SN-4 weighs about 4oz more than a TA31 (weighs the same as a TA11), it is 4" longer than a TA31 (about an 1" longer than a TA11). Most distinguishing feature of the SN-4 is the adjustable turrets. I think I noted a deal over at the hide for SN-4s for about $1k. As for the much discussed "battery life" factor - umm big deal would be what I would say. Those that make a bunch of noise about it most likely don't shoot much in fading light or total darkness. Truth be told, short of NV your hits really fall off when it gets dark - think about it - yeah you can see your ret - but you can't see your target - how does this help? What does help (to a degree) is adjustable brightness. Last night I shot from 5:00 (dim light) to 6:15 (dark) with an M-4 and an Aimpoint from 25 to 328 yrds. As the light faded I needed to turn the brightness WAY down esp for the 328 shots. Also think about when the target is lit (standing under a street lamp) - guess what? you can see the black stadia of your ret just fine. In short, unless it is a dot I would put more emphasis on adjustable brightness than battery life. IMHO, an ACOG is about as good as it gets for an all around optic, however it is not a precision optic. If your emphasis is on precision you need adjustable turrets. Good luck |
The SN-4 actually weighs considerably more when you factor in its mount, which is much more massive than the standard ACOG mount. As for adjustable brightness the ACOG does have this feature. When the ambient light begins to decreases the reticule adjusts accordingly, then when there is little ambient light and the tritium kicks in it is a nice dull orange color that works very well in the dark. The only think you have a one up on is shooting from dark to say under a streetlight. Yes your reticule is going to wash out, but you are still left with a black donut or chevron or triangle, that should be plenty of contrast between reticule and the lighted target to make the shot. As for the staida lines not being lit, who the hell is making a shot past 300 meters at night, at a target they can not see.
I would have to dissagree, I have pegged shots all day on a chest of a target at 500 meters with my west coast with a TA31 and Head shots through my donut of death all day at 300 meters. If you want any more precison than that from a 4X optic then you might want to rethink your options to say a MRT. Matt Carper |
