Description
The Trijicon ACOG 4×32 (model 100309, TA31-D) is a fixed-magnification combat riflescope built around an Illuminated Red Chevron .223/5.56 BDC reticle. The reticle is calibrated for .223 Remington / 5.56 NATO flattop rifles, with the chevron tip designed to be zeroed at 100 meters and bullet drop compensation holds extending out to 800 meters.
This version is finished in OD Green and includes the TA51 mount. The dual-illuminated reticle is powered by tritium and fiber optics – no batteries required – and provides a bright, always-on aiming reference in any lighting condition from daylight to low light.
Optical and mechanical specifications include 4x magnification, a 32mm objective, a 36.80 ft @ 100 yds field of view, and 1.50″ of eye relief. The optic measures 5.80″ long and weighs 15.10 oz. Adjustments are made in .25 MOA clicks at 100 yards, and the multi-coated lenses are housed in a fogproof, waterproof, and shockproof body built to military standards.
The chevron reticle is a refined combat aiming point: the base of the chevron measures 5.53 MOA (approximately 19 inches at 300 meters), giving the shooter fast target acquisition and precise holdover for the .223/5.56 platform.
