Trijicon ACOG 4×32 LED | 300 BLK | TA51 Mount

The Trijicon 4×32 LED ACOG is a fixed-power combat optic with an illuminated red 300 Blackout-calibrated reticle and an included TA51 flat-top adapter. It uses a single AA battery for selectable brightness settings and retains the rugged forged 7075‑T6 aluminum housing common to ACOG models. The merged supersonic and subsonic BDC reticle is designed to provide a unified set of aiming points for 300 Blackout ammunition without re-zeroing between supersonic and subsonic loads.

Built to the ACOG standard of ruggedness and battery-powered illumination, this optic is well suited to precision short- to mid-range shooting and to range work where rapid transitions between supersonic and subsonic 300 Blackout loads are required. The combined BDC aiming points simplify holdovers across common commercial ammunition while the compact form and TA51 mount keep the package low-profile on flattop upper receivers.
