Trijicon ACOG 4x32mm Dual Illuminated Red Chevron Riflescope

The Trijicon ACOG (Advanced Combat Optical Gunsight) TA31RCO-M4CP is a fixed 4x magnification riflescope designed specifically for the M4 and M4A1 weapon systems with 14.5-inch barrels. Developed to United States Marine Corps specifications, this combat-proven optic delivers reliable field performance.

Featuring dual illumination technology, the ACOG combines self-luminous tritium with fiber optics to keep the aiming point perpetually lit without batteries. The tritium provides visibility in total darkness while the fiber optic system automatically adjusts reticle brightness based on ambient light conditions in daylight.

Designed for maximum situational awareness, this optic allows the operator to engage targets with both eyes open. The reticle incorporates a Bullet Drop Compensator for accurate holdover out to 800 meters. External windage and elevation adjusters require no tools, simplifying field adjustments. Waterproof construction is rated to 11 meters without adjustment caps.
