Trijicon ACOG TA31-D-100219 4x32mm Red Horseshoe BDC Scope

The Trijicon ACOG TA31-D-100219 delivers battle-proven optical performance with its dual-illuminated 4x32mm design and .223/5.56 BDC reticle. This combat optic combines tritium and fiber optic illumination to maintain reticle visibility across all lighting conditions without batteries.

What Makes This Different

Unlike battery-dependent optics, this ACOG uses Trijicon's patented dual-illumination system that automatically adjusts brightness based on ambient light. The red horseshoe reticle provides rapid target acquisition while the BDC (Bullet Drop Compensator) enables precise shots from 100 to 800 meters with standard .223/5.56 ammunition. The 4x magnification offers the ideal balance between target identification and situational awareness.

Key Features

• Dual-illuminated red horseshoe reticle with tritium and fiber optic technology
• 4x magnification with 32mm objective lens for optimal light transmission
• BDC reticle calibrated for .223 Remington and 5.56x45mm NATO ammunition
