Trijicon ACOG TA31F 4x32 Green Donut Reticle .223/5.56 BDC

The Trijicon ACOG TA31F delivers combat-proven magnified optics with tritium and fiber optic dual illumination that never needs batteries. This 4x32mm scope provides clear target identification at extended ranges while maintaining situational awareness through its generous 36.8-foot field of view at 100 yards.

What Makes This Different

Unlike battery-dependent optics, the TA31F combines tritium and fiber optic technology for automatic brightness adjustment in any lighting condition. The green donut reticle offers rapid target acquisition with precise aiming capability, while the Bullet Drop Compensator (BDC) provides holdover points calibrated for .223/5.56 ammunition. This fixed 4x magnification eliminates the complexity and potential failure points of variable power scopes.

Key Features

• Dual illuminated green donut reticle with tritium and fiber optic technology
• Fixed 4x magnification with 32mm objective lens for optimal light gathering
• BDC reticle calibrated for .223 Remington and 5.56x45mm NATO ammunition
• 36.8-foot field of view at 100 yards for enhanced situational awareness
