Trijicon 100219 ACOG 4x32mm Illuminated Red Horseshoe .223/5.56 BDC Riflescope - Black Hardcoat Anodized

The Trijicon ACOG 4x32 (TA31H, MPN 100219) is a battle-proven fixed-magnification combat riflescope calibrated for the .223 / 5.56x45mm NATO cartridge. It features the iconic illuminated Red Horseshoe reticle with a calibrated .223 / 5.56 BDC holdover system designed for flattop rifles out to 800 meters. Built around a rugged forged-aluminum housing finished in Black Hardcoat Anodized coating, this ACOG is engineered for hard use on service carbines.

Trijicon's dual-illumination system pairs advanced fiber optics with self-luminous tritium to keep the reticle lit without batteries or switches. The ACOG's multi-coated 32mm objective gathers light for a clear sight picture, and windage/elevation adjustments click in precise 0.25 MOA increments at 100 yards. With a constant 36.8 ft @ 100 yds field of view and 1.5" of eye relief, the optic provides fast, both-eyes-open aiming well-suited to close-to-mid-range engagements.

Sealed and nitrogen-purged, the ACOG is fogproof, shockproof, and waterproof for reliable performance in harsh field conditions. The compact 5.80" tube adds just 15.10 oz to the host rifle and ships with the TA51 thumbscrew mount for fast installation on a Picatinny rail. One of the most recognized and respected combat optics in service today, the Trijicon ACOG 4x32 Red Horseshoe BDC is a true gold-standard fighting scope.
