Trijicon 4x32 ACOG® Scope, Dual Illuminated Red M 855 RCO Reticle

With LaRue Tactical® LT799 Mount 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.
