The Trijicon ACOG is arguably the most combat-proven optic ever made, and the TA31 is the model that earned that reputation across two decades of military service. What makes it remarkable is that it needs no batteries at all: a fiber optic strand on top and a tritium vial inside light the reticle, brightening in daylight and glowing at night, so it is always on. Trijicon's Bindon Aiming Concept lets you shoot with both eyes open for fast close-range work while still getting 4x magnification for distance.

This configuration uses a red horseshoe-dot reticle calibrated for .223 and includes the TA51 flattop mount.
