The Trijicon ACOG is one of the most combat-proven optics ever built, and the TA31 is the model that served through two decades of American military use. It needs no batteries at all: a fiber optic strand on top gathers ambient daylight and a tritium lamp illuminates the reticle in darkness, so the sight is always on and cannot be switched off or run flat. This version uses the green horseshoe and dot reticle with the Bindon Aiming Concept, which lets you shoot both eyes open at speed, and a bullet drop compensator calibrated for 5.56 ammunition. Includes the TA51 flat-top mount.
