The Trijicon ACOG 2×20 Compact Scope (brand part no. TA47-C-400416) pairs 2x magnification with a green illuminated reticle for AR-15 shooters who want a bit more target identification range and prefer green over red. Trijicon forges the housing from 7075-T6 aircraft-grade aluminum and illuminates the RTR horseshoe-dot reticle with fiber optics for daylight brightness and tritium phosphor for total darkness, so no battery is ever required. The reticle is calibrated for 55-grain .223/5.56 loads for genuine bullet-drop holdovers, and the Bindon Aiming Concept lets shooters keep both eyes open for fast target transitions. The factory-equipped, tool-less Q-LOC Picatinny mount makes install and removal quick and repeatable. Among our gun scopes, this green-reticle 2×20 Compact ACOG suits AR-15 shooters who want extra reach without giving up Trijicon’s no-battery reliability.
