OVERVIEW
The TA31USN-M855 is an Advanced Combat Optical Gunsight (ACOG) designed for either the M16A4 weapon system (20” barrel) or the M16M4 (14.5” barrel). It incorporates dual illumination technology using a combination of fiber optics and self-luminous tritium. This allows the aiming point to always be illuminated without the use of batteries. The tritium illuminates the aiming point in total darkness, and the fiber optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness. The unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 1,000 meters utilizing the Bullet Drop Compensator. No tools are needed for windage and elevation adjustments because the TA31USN-M855 features external adjusters, making it waterproof up to 11m without the caps.

ALWAYS ON, ALWAYS READY
Most ACOG® models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.
TAKE CONTROL
Several ACOG models are designed with a user adjustable brightness setting powered by a single AA battery. The 3.5x35 LED and 4x32 LED models both offer six adjustable brightness settings.
RUGGED, RELIABLE HOUSING DESIGN
Fixed-power design allows for minimal moving parts to create a nearly indestructible sighting system.
“BOTH EYES OPEN” DESIGN
“Both eyes open” shooting using Trijicon's Bindon Aiming Concept™ (BAC) feature allows for improved situational awareness.
OUTSTANDING CLARITY
The quality of the glass and multi-coated lenses maximize light-gathering capabilities and clear field of view with zero distortion.
EXACT TARGET DISTANCES & HOLDS
Most ACOG models feature a bullet drop compensating and target-ranging reticle for decisive aiming.
COMBAT PROVEN
No other magnified optic has been used more in combat than the ACOG.
SHOCK-RESISTANT
Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.
WATERPROOF
Exceptional waterproof performance that exceeds military standards. Dry nitrogen-filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry-nitrogen filled housing that mitigates fogging.
INDUSTRY-LEADING RESEARCH, DESIGN & TESTING
We are engineers at heart, like our founder, Glyn Bindon. Therefore, we are bound by a commitment to seek innovative aiming solutions that constantly redefine “brilliant.” This legacy of innovation is fed by what we call The Science of Brilliant®.
