Trijicon ACOG 4x32 .223/5.56 BDC Green Crosshair Scope TA31F

The Trijicon ACOG 4x32mm delivers combat-proven optical performance with its illuminated green crosshair reticle specifically calibrated for .223/5.56 ammunition. This fixed-power scope combines tritium illumination with fiber optics to maintain reticle visibility in all lighting conditions without batteries.

What Makes This Different

Unlike variable power scopes that can fail under stress, the ACOG's fixed 4x magnification eliminates moving parts while providing optimal target engagement from close quarters to 600 meters. The Bindon Aiming Concept allows shooters to keep both eyes open, maintaining peripheral vision while engaging targets. Tritium illumination remains functional for over 15 years, requiring no external power source or maintenance.

Key Features

• Dual-illuminated green crosshair reticle combines tritium and fiber optics for 24/7 visibility
• Bullet Drop Compensator (BDC) calibrated for 55-62 grain .223/5.56 ammunition
• 4x32mm objective lens with multi-coated optics for superior light transmission
• Hardcoat anodized aluminum construction rated for combat conditions
• Waterproof to 11 meters and shockproof to withstand repeated recoil
• Mounts to standard MIL-STD-1913 Picatinny rails without modification
• Eye relief of 1.5 inches accommodates various shooting positions

Field performance remains consistent across temperature extremes from -40°F to 160°F. The BDC reticle provides holdover points for targets at 100, 200, 300, 400, 500, and 600 meters when zeroed at 100 meters. Law enforcement agencies and military units rely on this optic for its ability to function without adjustment in diverse environments. The 32mm objective diameter balances light gathering capability with compact profile for tactical applications.
