TA31RCO-M4CP: 4x32 Trijicon ACOG® USMC Rifle Combat
Optic (RCO) with Red Dual Illuminated Reticle
The TA31RCO is an Advanced Combat Optical Gun sight (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.
