The Trijicon ACOG 4x32mm is a compact, internally adjustable combat riflescope built around Trijicon’s Bindon Aiming Concept (BAC), which lets shooters keep both eyes open for fast, instinctive target acquisition (model 100310). It features a dual-illuminated reticle that combines fiber optics for daylight brightness with tritium for illumination at night, so it never needs a battery, with a red chevron aiming point, calibrated for .223/5.56 NATO.
