Trijicon ACOG 4×32 Red Crosshair .223 | TA51

The Trijicon ACOG 4×32 is a fixed-power riflescope designed for consistent aiming across a wide range of light conditions. It uses fiber optics and tritium for dual illumination, providing a bright reticle for daylight and low-light use without batteries. The reticle is ballistically calibrated for .223/5.56 to provide bullet drop compensation for intermediate-range engagements. The scope is built with a forged-aluminum housing and a TA51 flattop thumbscrew mount for direct attachment to flat-top rails.
