Trijicon ACOG USMC RCO 4x32mm – Red Chevron M16A4 .223 / 5.56 BDC Reticle

The Trijicon ACOG USMC RCO is an Advanced Combat Optical Gunsight (ACOG) designed for the USMC’s M16A4 weapon system (20” 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. 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 Trijicon ACOG USMC 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).

Bindon Aiming Concept with the Trijicon ACOG USMC RCO

Although human vision is based on a binocular or two eyed vision of an image, traditional riflescopes present a monocular view of the target. This monocular view significantly decreases vision capabilities and makes it difficult to acquire and track targets.

Traditionally, “both eyes open” aiming has been widely used with iron sights or reflex style sights, but use with a magnified scope was often deemed implausible. The Bindon Aiming Concept (BAC) is a method of combining “both eyes open” aiming while using a magnified scope.

Shooting with “both eyes open” offers several advantages to the user: better situational awareness, a far superior sense of balance, a wider field of view, and far less eye strain. These advantages aid the shooter in quick target acquisition and improved shooting performance.
