Questions & Answers
How is this on a 11.5 in barrel AR15? Expert Answer

The Trijicon ACOG 3.5x35 Scope w/ TA51 Mount with the TA11H and TA11H-G reticle are designed for 16" barrels. It will still work with your 11.5" barrel, however, the holds and hashmarks may not be accurate to your point of impact after zeroing.

Will this align with iron sights? Expert Answer

The Trijicon ACOG 3.5x35 Scope w/ TA51 Mount sits at an absolute co-witness height of 1.4" (centerline). This means it would align with traditional AR15 iron sights. However, this is a magnified optic, you won't be able to use your iron sights with the optic as they will be out of focus.

I'm used to running an EoTech with a tripler while I served in the military for 10 years. Upon getting out, I ran an LPVO on my AR platform. I liked the thought of not having to run out of batteries in a worse case scenario, however, an LPVO still re...

Spot On Glass by Floyd, Verified Owner, March 9, 2015
This is my 2nd Acog. Have one for my .223 as well. With the horseshoe reticle, target acquisition is even quicker than my older model with the triangle reticle. Clarity is great for the 400-500 shots. It becomes a part of the rifle.

Robert Keesling by Floyd, Verified Owner, April 7, 2015
This is my 3rd ACOG, which I think is one of the finest scopes available. Target acquisition is very quick, clarity is excellent. The included description on ranging is very clear and easy to understand, which leads to the "quick to acquire" the ta...

ACOG for my .308 by Scott, March 9, 2017
Amazing optics from this scope. The numbers on the mil dots/hash marks are very small so if you have old eye be forewarned. (once you know what they say its less of an issue but even then they are a bit small) Other than that I sighted it in, and ...
