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!

With a rich history of contracts and optics that simply have no equal, the 3.5x ACOG for .308s is a solid choice for fixed magnification optic. When others have gone shooting with me, I do have to explain to them how to shoot with both eyes open. The ability to do so is a major reason to stick with an optic of this kind. In a day and age of red dots with magnifiers and LVPOs, the ACOG stands apart by having this capability as well as the lack of batteries. As the tide of red dots has long entered the realm of shake-awake dots and batteries that last several years, the biggest benefits to the ACOG revolve arould the magnification, the reticle, and the ability to mount a micro red dot directly to the top. With the optic on a weapon I let friends and shooters new to .308 use, it has had several bumps and scrapes. Mine has not experienced cracked glass, loss of zero, or reticle tilt at all. I am amazed and grateful for the quality that is associated with Trijicon. For the price, there are so many options available. My recommendation in this optic is for the explicit use on 14-18 inch firearm with detachable magazines. I would purchase this again if I had a similar build again.

I put this on my scar 17 as I have a precision rifle/scope combo for further precision shooting beyond the abilities of this 3.5 acog or my 16" barrel. That said, this optic is truly amazing. I would recommend anyone that is on the fence go ahead and take the plunge. I ordered mine 9-11 and received it 2 days later. I called trijicon to get the manufactured date and was told it was only 5 months old. Not bad considering the tritium won't need replaced for 14.5 years or so for me. Crystal clear glass, second-to-none ruggedness, and battle proven time and time again. I don't spend money easily on myself but can say 100% honestly that I have ZERO buyers remorse here. If you have a weapon platform you want to dedicate to quick target acquisition and reliable performance you can't go wrong here in my opinion. Also, if you have a weapon that's hard on optics (large caliber or really pronounced 2 stage recoil such as my scar) I highly recommend this setup. I also recommend you check out the la rue lt100 mount for it. That second photo's holding the scope with one hand the cell with the other looking through a dirty window with blinds and screen so not a good representation of clarity but it gives you an idea the size of the reticle. It might look a hair bigger with your eye closer than my camera but this is more less what you're getting

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.

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

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.

I was hesitant to pay this much for an optic but once I got over the sticker shock I have become a believer. I mounted this on my Daniel Defense AR which replaced my Aimpoint Patrol Comp red dot optic. I really liked the Aimpoint but if you are looking for an optic at some point you will have to decide between a magnified optic or red dot sight without magnification unless you want to add a magnifier. The ACOG to me has two cons that are more about choice rather than actual issues. First, if your looking for speed and engaging targets up close the red dot is the way to go. Even though with practice the ACOG will function it will never be as fast as a non magnified red dot like an Aimpoint or EO Tech (in my opinion). Two, you have to take into consideration the eye relief (distance from the optic that the sight picture becomes clear / full) of the ACOG you are purchasing. I purchased the 3.5 because it has the most eye relief and is perfect for my AR other than the fact I had to mount it all the way to the back of the AR meaning my back up flip sights had to go in front. Like I said this is a great product but you need to understand the situation you are most likely to use this weapon and optic combination and choose accordingly. You don't want to buy a hammer if you need a screwdriver.

Having owning many scope from cheap to expensive. I know for a fact that I do not compare it to a cheaper scope because majority of them are just not in the same league as Trijicon. Trijicon known for its' ruggedness and quality build overall. Glass is very clear specially this model which has a 35mm objective lens and has an eye relief of 2.4" compare to the more popular 32mm model which is only 1.4". It's hard to choose which model to get but I know from experience that bigger objective means brighter view. 3.5x fix zoom is just about the perfect size IMO for most task unless you really want to see where/what you're hitting from beyond 100yd range then by all mean, Trijicon Accupoint is the way to go. The green illumination fiber & tritium is the most expensive model of the three choices they have (Red, Green, Amber). Fiber is bright in the day and could be blinding on a very sunny day. A black electrical tape will help cover up the plastic fiber atop the scope to reduce green glow. I do have a little complaint on my somewhat dim tritium or maybe it's just me. Also, green is by far the easiest color to see at least for me. Why waste all those money buy dozen of cheap scope that can break with a bump when you can have just one that you can count on with your life? Sure, you might think nothing will happen to you and you will never need a scope as good as this, but you never know. No country is bullet proof that can escape SHTF moment. Beside, Trijicon product holds value better than most scope so you know you can always get majority of your investment back as long as you keep it in a good condition. Even an ok condition scope, you can get half of your investment back. This is a wise investment as the mighty Dollar keep falling every day. It's like buying gold except you can use this right away. Go ahead, spoil yourself and get this baby home. Side note: Make sure you buy it from reputable seller, one that is an actual Trijicon dealer (Amazon, Opticplanet, etc...) and not individual sellers. There are alot of fake out there so beware. Search "fake Trijicon Acog" on the web and you'll know what I mean.
