Trijicon 100091 ACOG 4x32mm .223 BDC Illuminated Amber Crosshair Riflescope - Black Hardcoat Anodized

The Trijicon ACOG (Advanced Combat Optical Gunsight) is a combat-proven, fixed-magnification riflescope built around a 4x magnification and a 32mm objective lens. This TA01NSN configuration is the battery-free, dual-illumination model designed to the exact specifications of the US Special Operations Command, the same optic carried on the M4A1 carbine by US armed forces.

The reticle is an Illuminated Amber Crosshair .223 BDC, combining tritium and fiber optic illumination for automatic brightness adjustment without batteries. The crosshair appears black in daylight and glows amber in low-light and no-light conditions. The bullet drop compensation (BDC) ladder is calibrated for .223 and provides accurate holdovers out to 600 meters without manual adjustment.

The ACOG housing is machined from forged aluminum and finished in black hardcoat anodized for maximum durability. It is fogproof, waterproof, and shockproof, with multi-coated optics for superior light transmission and image clarity. Trijicon's legendary combat-proven standards make the 4x32 ACOG the gold standard of fixed-magnification combat optics.

Specifications include a 36.80 ft field of view at 100 yards, 1.50 in eye relief, 5.80 in overall length, and a 14.96 oz weight. Adjustments click at 2 clicks per inch at 100 yards. Whether mounted on a duty carbine, defensive rifle, or recreational platform chambered in .223, the Trijicon 100091 ACOG delivers proven ruggedness and repeatable accuracy in any lighting condition.
