Trijicon ACOG 4x32mm USMC RCO Red Chevron Riflescope

The Trijicon ACOG 4x32mm USMC RCO (Rifle Combat Optic) is a combat-proven riflescope designed to the exact specifications of the United States Marine Corps for the M16A4 weapon system with 20-inch barrel. It features dual illumination technology combining fiber optics and self-luminous tritium, providing a continuously illuminated aiming point without batteries.

The fiber optic automatically adjusts reticle brightness based on ambient light conditions, while tritium ensures visibility in total darkness. This system allows operators to maintain both-eyes-open targeting for maximum situational awareness. The unique reticle pattern provides quick target acquisition at close combat ranges while the integrated Bullet Drop Compensator enhances target identification and hit probability out to 800 meters.

Built for field durability, this scope features external windage and elevation adjusters requiring no tools, waterproof construction tested to 11 meters without caps, and anti-reflection device included. Integrated mounting bosses on the eyepiece allow easy addition of a Trijicon RMR (not included). Includes TA51 flat top mount for direct attachment to AR-15 platform.
