Trijicon ACOG RCO 4x32mm

Designed to the exact specifications of the United States Marine Corps, the unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters utilizing the Bullet Drop Compensator.

No tools are needed for windage and elevation adjustments because the TA31RCO features external adjusters, making it waterproof up to 11m without the caps. Mounting bosses are integrated into the housing by the eyepiece to allow the easy addition of a Trijicon RMR® (not included).

ACOG RCO 4x32mm Features

Features a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

Forged 7075-T6 aircraft aluminum-alloy housing provides for a nearly indestructible sighting system.

The ACOG can be used as a CQB sight when shooting “both eyes open,” utilizing the Bindon Aiming Concept (see below).

Multi-coated lenses provide superior clarity and light-gathering capabilities with zero distortion.
