Tenebraex acog - Trijicon TA66 Tenebraex killFLASH Anti-Reflection Device for 3.5x35 ACOG Scope

Appears and works as intended. I dont plan on beating up my ACOG so I couldnt tell you what happens when it takes a dive, however, it appears to be legit. The ARD is good idea if you want to hide your glare or scope flash. It pretty much vanishes once aiming the weapon as it was intended, so you can only see the lines when looking from an alternate or non aiming view. This along with some blue locktite on your TA51 or even an alternate mount are good ideas for the ACOG platform regardless of designation TA31,33,11.
