There is absolutely no question, the ACOG TA31 is one of the nicest looking sights on the market today…especially on M4’s!
This particular replica from G&G features a functioning fibre optic, which illuminates the reticule. It uses ambient light to charge the red of the reticule, making it easier to aim. As such you do not need any batteries, nor do you have to fiddle with any switches or knobs etc to toggle it on/off.
Designed for M4/M16 rifles, this sight completes the look of the gun, and matches much of what you see in Hollywood. The eye relief on this particular model is excellent, but in context…it’s good for an ACOG. You will still need to mount it as close to your eye as possible.
Where this optic sets itself apart from the crowd is in its clarity – it is crystal clear, and makes aiming a dream.
