Trijicon ACOG TA31RCO 4x32 Red Chevron 223 Remington Rifle Scope

The Trijicon ACOG TA31RCO is a 4x32 rifle scope built to the US Army's M4 weapon system specification for a 14.5-inch barrel. It uses an illuminated red chevron reticle with a .223 Remington bullet drop compensator, intended for quick target acquisition at close range and aimed fire out to 800 meters.

The optic combines fiber optics with self-luminous tritium to keep the aiming point lit without batteries. Tritium illuminates the reticle in total darkness, while the fiber optic adjusts brightness in daylight according to ambient light. The scope weighs 1.01 pounds, measures 7.3 inches overall, and has a matte black finish with a 32mm objective and external windage and elevation adjusters.

The scope mounts on a TA51 Flattop mount, which fits the flattop rail of the rifle. No tools are needed for adjustments.
