Trijicon ACOG RCO 4x32 Scope – Red Chevron Reticle for M16A4

The Trijicon ACOG RCO 4x32 delivers fixed 4x magnification with the classic red chevron reticle, designed specifically for the M16A4 platform. This combat-proven optic uses Trijicon's dual-illumination system—tritium and fiber optic—to keep the reticle visible in any light condition without batteries. The chevron reticle provides quick target acquisition at close range and precise holdovers for extended distances, making it effective for patrol, competition, and tactical applications.

Built with forged aluminum housing, the ACOG is waterproof to 100 meters and fog-proof. The scope mounts directly to the Picatinny rail with the included TA51 mount, designed for proper eye relief and height on AR-15/M16 platforms. Trijicon's BAC (Bindon Aiming Concept) allows shooters to keep both eyes open for enhanced situational awareness. External adjustments are precise and repeatable, with windage and elevation controls protected under caps.
