Trijicon ACOG 4x32 Red Horseshoe/Dot M855 RCO Reticle TA31-D-100581

Overview

The Trijicon ACOG (Advanced Combat Optical Gunsight) is a 4x32 dual-illumination optic renowned for its durability and reliability in demanding conditions. Designed to the exact specifications of the United States Marine Corps for use on 20-inch M16A4 and 14.5-inch M4/M16 weapon systems, this battery-free sight utilizes a combination of internal fiber optics and self-luminous tritium. The fiber optics automatically adjust reticle brightness during daylight conditions, while the tritium illuminates the red horseshoe and dot reticle in total darkness. Featuring the Bindon Aiming Concept, the optic allows operators to keep both eyes open for rapid target acquisition and situational awareness. It incorporates a bullet drop compensator calibrated for .223/5.56 ammunition out to 1,000 meters, tool-free external 1/10 milliradian windage and elevation adjusters, a forged aluminum housing waterproof up to 11 meters, and a TA51 thumbscrew mount. Included accessories consist of a Scopecoat, a Lenspen, adjuster cap lanyards, and an RCO manual.
