Ok, I have been waiting to get an ACOG sight for about 6 years now. I wanted the Trijicon, but as expensive as they are, it was cost prohibitive. Then along comes a lightening deal from Amazon and all is right in the world! I have debated terribly on which scope, which reticle, and which color to get. I ended going with this one and can honestly say that I have no regrets! I am sure that if you are in the market for one of these, you are doing extensive research as well. My biggest concern was size with this one as it is much larger than the 4X Trijicon, and you lose some eye relief. I really liked the 4X, both for the magnification and the size of the scope. However, after much debate, eye relief won out and this is why I ended up with this one. I HIGHLY recommend that you take a look at these in you local shop if you can. If not, do extensive research on any and all items that you are thinking about. There is a lot of helpful information out there (as I well know from hours and hours on the computer for this one). Reticle choice is personal, but I really like the horseshoe. My second choice would be the chevron reticle. There are pros and cons to each, but in the end I really liked having the dot on target with the reference ring around it vs just putting the target at the point of the chevron. As far as color is concerned, this is again very personal. This is the first green illuminated scope that I have owned, and I have no regrets in getting this. I do feel that the red it a bit easier to see, but the green is not as 'harsh' on the eyes in my opinion. Again, to each their own, but I am happy with the green reticle on this one. Build quality is typical Trijicon and is the epitome of how a scope should be constructed. I do have to admit that the first one I received had a dark area on the ring of the reticle at the lower left corner. I lived with it for about 2 weeks, then couldn't take it anymore and had Amazon exchange it. Exchange was easy and the new one was perfect! God I love Amazon! But that is a whole other conversation. Now, I know that size is another issue that you will see comes up in your research on this item and it is quite a bit larger than the 4X Trijicon. I have to admit, this baby takes up a LOT of real estate on the rifle top and it is NOT light. That being said, it looks absolutely incredible on a weapon! I know that looks should not play a part in the decision process, and it didn't in mine, but I have to say that I think that this scope looks better on a weapon than the 4X just due to the sheer size. If you see that size and weight as a detriment, the offset of it is eye relief and ability to keep both eyes open with better targeting due to that eye relief. The .5 magnification is really quite negligible in the big picture. Not a huge advantage for the 4X, and not a huge disadvantage to the 3.5X. Do not be alarmed when yours arrives without a Pelican case as Trijicon has discontinued doing this and this ships in a cheap, thin plastic container but is well packed and protected inside. Truth be told, if the optic is going to be on a weapon, then a fancy case does no good anyway. I am very happy with this purchase and am finally glad to have this be the crown jewel on my custom AR. You will not regret this purchase!

ACOG sights are seriously in their own league. I was torn between the TA11-F (this one) and the TA31-F but ended up going with this one due to the longer eye relief which is more forgiving at weird angles. Amazon lists this ACOG as a TA11-A but the title says red chevron which really makes it a TA11-F. It comes in the nice trijicon ACOG box with a manual, sticker, cleaning brush, and cover. The glass on the ACOG is phenomenally clear and the red chevron is easy to see in the daylight or complete darkness thanks to the tritium gas. The long eye relief on this allows you to place the sight further away from your person on your top rails and still get a good picture. It is much larger than some of the other ACOG sights and heavier but unless you're running around with the rifle it doesn't really matter. The BAC technology allows you to shoot with both eyes open. If you move the sight over an object that is very close your dominant eye will allow you to see the chevron while your secondary eye will be actually focused on the close object. As you transition to an object further away you'll notice your brain chooses to use your dominant eye to focus on the target through the glass automatically. It's a bit tough to get used to for some people and can take some practice. Zeroing the sight is fairly easy and is accomplished just like any other scope. For this TA11F you'll want to zero it to the tip of the chevron at 100yds. After each adjustment of the knobs be sure to give the knob / sight a good whack with the other end of your screwdriver to "settle" the optic inside. You don't have to abuse it, but ACOGs generally require a good tap or two after you adjust the knobs. Don't ask me why, that's just what i've read and do. The ACOG is tall enough to fit over most back up sights that flip up (like the magpul ones). I mounted it on top of a Sig 556 and it barely clears the rear rotary diopter iron sight by Sig. You may need an adjustable cheek weld on your stock to line up perfectly as it sits a bit high but I haven't had much trouble with it. The price is a bit steep for this bad boy (as with all ACOGs) but I have no regrets.

This is an amazing scope. The US military uses it, so it must be pretty good. The only thing I would do is to get the red dot on the top which is a bit more money, but I think it would be worth it. The Trijicon is really amazing though, and helps these old eyes see a target that I could have seen without any magnification before. There are other decent cheaper scopes, but if you want the best get this one

I mounted this sight directly to an ACOG-specific mount on a FAL PARA. This is well worth the high cost of admission. The optic is bomb-proof. I dare say the rifle will probably fail before the optic does! You don't need batteries - the fiber optic and tritium gas illuminate the reticle. The glass is very clear and high quality. The chevron and ranging stadia are simple to use. The Bindon Aiming Concept - using both eyes and focusing on the target, not the reticle - takes some practice. At close range, you just paint the chevron on the target and fire. The cost of using a flip-to-side magnifier with a dot sight is almost comparable to this ACOG, but with very little advantage. The M-16 carry handle iron sight channel works just as well on the FAL - you can use the factory iron sights through the channel, though you'll really need a stock without a cheek riser to use the irons - with the riser to use the ACOG. Pic attached is of this ACOG on the FAL PARA. Out of the box, mine shot 18" low and 6" right. Within 40 rounds I was sighted in and ringing steel gongs at 200 yd.
