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.

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!

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 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
