This is my first ACOG. It is very clear and bright. The Amber color reticle is much easier to see than Red. My eyesight is rather poor so the very fine small lines that makeup the drop ballistic lines is too small for me to see. Also, they squeez...

ACOG is the Best by Deer Stalker, Verified Owner, October 22, 2017
From the recommendations I received, I expected the ACOG 3.5x35 to be a great scope! I was not disappointed. It has preformed flawlessly. I have this on on one of my AR15s. I am saving up to get one for my AR10. Makes it twice as much fun to sho...

Great but be carefu which reticle color you get by Dan, Verified Owner, April 27, 2022
The TA11 is probably the best all-round ACOG in the whole lineup. I live in Florida and really should have guessed the Green reticle is probably not the best option for this biome. This is a fantastic optic and I really have no complaints apart from ...

Bad Bad Bad by Nick, March 7, 2016
Awsome awsome scope. I can see why people spend the money on these. I was concerned with how big the TA11 was until I saw it. It looks like an average scope and so now I realize that the TA31s are sorta small. Green Chevron is beautiful. Perfect br...

TA11F-R by Legacy Reviewer, November 17, 2012
Vary happy with the purchase. The extra eye relief of the TA-11 sold me over the TA-31. If your a nose to charging handle AR shooter the TA-31 might be your choice. Pros: Clarity and eye relief Cons: price

Product Info for Trijicon TA11F-A ACOG 3.5x35 Rifle Scope - Chevron BAC .223 Flattop Reticle with Flat Top Adapter

Trijicon TA11F ACOG 3.5x35 Scope with Chevron BAC Reticle includes Trijicon Flat Top Adapter TA51. The ranging reticle of the Trijicon Gunsight is calibrated for 5.56mm (.223 cal) flat-top rifles out to 800 meters. The chevron reticle is designed to be zeroed using the tip at 100 meters. The width of the chevron at the base is 5.53 MOA which is 19" at 300 meters. This allows range estimation for silhouette targets. Trijicon TA11F-A 3.5 x 35mm ACOG Advanced Combat Optical Gunsights hit fast in any light. Trijicon ACOG 3.5 x 35 Rifle Scopes are internally-adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. Bindon Aiming Concept (BAC) models feature bright daytime reticles using fiber optics which collect ambient light. Trijicon 3.5x35 ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Although Trijicon ACOG 3.5 x 35 Rifle Scopes TA-11F have many features which are very advantageous for military use, they were developed by Trijicon without government funding. Designed for use with the M16 family, every feature of its mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions - without failure-prone batteries.image
