Trijicon 100220 ACOG 4x32mm Illuminated Red Horseshoe w/ Red Dot 6.8 SPC Riflescope - Black Hardcoat Anodized

The Trijicon 100220 ACOG is a fixed 4x magnification combat optic purpose-built around the 6.8 SPC cartridge. This 4x32mm riflescope carries Trijicon's signature dual-illuminated Red Horseshoe w/ Red Dot reticle (Bullet Angle Compensation / BAC) calibrated to 6.8 SPC ballistics, giving shooters fast, intuitive holdovers out to extended ranges without having to dial the turret.

Built around a rugged forged aluminum housing with a black hardcoat anodized finish, the ACOG is internally adjustable, compact, and weighs just 15.10 oz. It measures only 5.80" in length and offers a generous 1.50" of eye relief. The 32mm objective pulls in plenty of light and pairs with multi-coated lenses to deliver a crisp sight picture across a 36.80 ft @ 100 yds field of view. Windage and elevation adjustment is positive and repeatable at 2 clicks per inch @ 100 yds.

The reticle is lit by Trijicon's proven dual-illumination system: fiber optics harvest ambient daylight for automatic daytime brightness while tritium takes over in low light and total darkness, with no batteries required. The optic is fully fogproof, shockproof, and waterproof, engineered to handle hard-recoiling rifles and harsh field conditions without losing zero.

This model ships complete with a TA51 flattop adapter for direct mounting to MIL-STD-1913 Picatinny rails. It is an ideal fixed-power combat optic for AR-platform rifles chambered in 6.8 SPC, delivering fast target acquisition, legendary Trijicon durability, and a battle-proven reticle system trusted by military and law enforcement.
