The Trijicon ACOG 1.5x16mm 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 TA44-C-400329). 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 green ring/dot aiming point.
