Trijicon ACOG 4x32 Red Chevron .223/5.56 BDC Rifle Scope TA31-CH

The Trijicon ACOG 4x32 delivers combat-proven optical performance with its illuminated red chevron reticle specifically calibrated for .223/5.56 ammunition. This fixed-power optic combines tritium and fiber optic illumination to provide a bright, clear reticle in any lighting condition without batteries.

What Makes This Different

Unlike variable power scopes that can shift zero or fail under stress, the ACOG's fixed 4x magnification maintains consistent point of impact through thousands of rounds. The dual-illumination system automatically adjusts brightness using ambient light during the day and tritium at night, eliminating the need for batteries or manual adjustments. The chevron reticle provides faster target acquisition than traditional crosshairs while offering precise bullet drop compensation out to 800 meters.

Key Features

• Dual illumination system combines tritium and fiber optics for 15-year maintenance-free operation
• Red chevron reticle with bullet drop compensator calibrated for 55-62 grain .223/5.56 ammunition
• Forged aluminum housing with hardcoat anodized finish rated for extreme temperature ranges
• Waterproof to 11 meters depth with nitrogen purging to prevent internal fogging
• TA51 flattop mount included for Picatinny rail systems
• 32mm objective lens with multi-coated optics for maximum light transmission
• Eye relief of 1.5 inches accommodates various shooting positions and protective equipment

Field testing demonstrates the ACOG's ability to maintain zero through temperature extremes from -40°F to 160°F. The scope withstands recoil forces from heavy calibers while the tritium illumination remains visible for over a decade. Military and law enforcement agencies rely on this optic for its proven durability in desert, arctic, and maritime environments. Competition shooters appreciate the consistent magnification and precise reticle graduations for rapid target engagement.
