Description
The Trijicon ACOG (Advanced Combat Optical Gunsight) model TA31-D-100288 is a fixed-power, compact 4x32mm combat riflescope purpose-built for .223/5.56 carbines. The iconic Red Chevron reticle is dual-illuminated by ambient-gathering fiber optics during the day and by tritium at night, so the aiming point stays visible around the clock with no batteries required.
Calibrated to Trijicon’s .223/5.56 BDC (Bullet Drop Compensating) hold points, the chevron allows fast, instinctive ranging and holdover out to extended distances. With a 5.53 MOA chevron base, the reticle works equally well for rapid close-quarters engagement and accurate mid-range fire. Multi-coated 32mm optics deliver a crisp sight picture, 36.8 ft of field of view at 100 yards, and 1.5″ of eye relief.
Finished in low-glare Matte Black, the ACOG measures just 5.8″ long and weighs 15.1 oz, giving a true 4x magnification step up from iron sights while staying compact and well-balanced on the rifle. Built to Trijicon’s battle-proven standards for hard field use, this configuration ships with the TA51 flattop mount for direct installation on a Picatinny rail.
