Trijicon ACOG 4x32 Dual Illuminated Red Chevron USMC Rifle Combat Optic (RCO) for M4 and M4A1 (14.5 in. Barrel) w/ TA51 Mount

The Trijicon fixed-magnification ACOG (Advanced Combat Optical Gunsight) line of rifle scopes represents one of the most durable and versatile optics in the world. It combines the precision of telescopic rifle sights with speed that rivals red dot sights thanks to its ingenious BAC (Bindon Aiming Concept) reticle. Dual-illumination is provided by tritium for low light or night time use and fiber optics add any available additional light to brighten the reticle to appropriate levels to match any situation.

The TA31RCO is an Advanced Combat Optical Gunsight (ACOG) designed for the M4 and M4A1 weapon system (14.5" barrel). Designed to the exact specifications of the United States Marine Corps, 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.
