Trijicon ACOG 4x32mm Chevron Red Illuminated Matte Black Finish 100228

The TA31RCO is an Advanced Combat Optical Gunsight (ACOG) designed for the US Army's M4 weapon system (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;m which allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness.
