Trijicon ACOG 4x32 W/TA51 Mount TA31RCO-M150CP-G

The TA31RCO is an Advanced Combat Optical Gunsight (ACOG) designed for the US Army's M4 weapon system. It incorporates dual illumination technology. A combination of fiber optics and self-illuminating tritium illuminates the reticle without the use of batteries. The tritium illuminates the reticle in low light situations, and the fiber optic self-adjusts the 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.

Designed to United States Military specifications, this unique reticle provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters using the Bullet Drop Compensator.

The TA31RCO features external adjustments. Eliminating the need for adjustment tools for windage and elevation. Waterproof up to 11m without the adjustment caps. Mounting bosses are integrated into the housing by the eyepiece allowing easy addition of a Trijicon RMR(not included).
