Trijicon ACOG TA31RCO 4×32 USMC RCO Chevron

Description

The Trijicon ACOG TA31RCO is a fixed-power, compact riflescope built to the USMC M16A4 RCO specification. It uses fiber-optic and self-luminous tritium illumination to keep the chevron reticle visible in bright light and in total darkness without batteries. The reticle incorporates a bullet drop compensator to aid holdover out to extended distances and is optimized for quick target acquisition with both-eyes-open shooting. Rugged forged-aluminum construction, external windage and elevation adjusters, and RMR-compatible mounting bosses reflect its design emphasis on durability and practical field use.
