The 3x24 Compact ACOG Riflescope from Trijicon features a battery-free illuminated ballistic reticle and a durable waterproof housing to create a versatile weapon sight that is well-suited for use in a wide range of weather and lighting conditions. This Advanced Combat Optical Gunsight (ACOG) sight is outfitted with a red crosshair reticle that has bullet drop compensation stadia on the lower vertical hair that are specifically calibrated for 123 grain 7.62x39 caliber ballistics. Anti-reflection broadband fully multi-coated optics maximizes light transmission to provide bright and clear views with limited distortion.
Trijicon's battery-free, dual-illumination reticle system employs a tritium phosphor lamp for low-light and night targeting, as well as a fiber optic illumination that automatically adjusts reticle brightness when operating in daylight. The reticle's aiming point can be adjusted in 1/2 MOA increments, and an internal adjustment mechanism allows the ACOG to reliably hold zero. Complementing the ACOG's optical system and caliber-specific ballistic reticle is a nitrogen-filled, aluminum housing with a scratch and corrosion-resistant hard-anodized matte-black finish that provides the durability needed for reliable performance in a wide range of shooting conditions. This ACOG is outfitted with a base that allows for the lowest possible mounting configuration. This achieves the desirable height above bore for the AK and other select firearm models with lower cheek welds, but a rifle-specific adapter must be purchased for installation. Mounting bosses are integrated into the housing near the eyepiece to allow the easy addition of a Trijicon RMR, available separately, with the RM54 mount, which also must be purchased separately.
