Trijicon ACOG TA31RCO-M4 4X32
The TA31RCO is an Advanced Combat Optical Gunsight (ACOG) designed
for the M16M4 weapon system (14.5 barrel). It provides the
shooter with quick target acquisition at close combat ranges while
providing enhanced target identification and hit probability out to
800 meters utilizing the Bullet Drop Compensator. The TA31RCO
incorporates dual-illumination technology using a combination of
fiber optics and self-luminous tritium. This allows the aiming point
to be always 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.
Designed to the exact specifications of the United States Marine
Corp, the unique reticle pattern provides the shooter with quick
target acquisition at close combat ranges while providing enhanced
target identification and hit probability out to 800 meters
utilizing the Bullet Drop Compensator.
