Trijicon ACOG TA31H-G | 4×32 Green Horseshoe/Dot

The Trijicon ACOG TA31H-G is a fixed-power 4x riflescope with a 32mm objective and an illuminated horseshoe-and-dot reticle calibrated for .223/5.56. It uses fiber optics for daylight illumination and tritium for low-light/night illumination, and ships with a TA51 flattop mounting adapter. The optical and mechanical design prioritize durable, battery-free illumination and a compact profile suitable for a flattop AR-style platform.

This optic is well suited for range and precision target work at intermediate distances and for field use such as varmint or small-game hunting where a quick, repeatable sight picture and a BDC-calibrated reticle are desirable.
