Trijicon ACOG 4x32mm Illuminated Red Chevron Reticle - Black Hardcoat Anodized

The Trijicon ACOG (Advanced Combat Optical Gunsight) is the U.S. military's battle-proven fixed-power riflescope, originally designed around the M4 carbine platform and fielded on service rifles across the U.S. Armed Forces. This configuration, the TA31RCO-M150CP, is the iconic 4x32mm combat optic with a battery-free dual-illuminated Red Chevron reticle that lights without any power source in any lighting condition.

The ACOG pairs tritium and fiber-optic illumination so the reticle comes on automatically the moment it's needed. The fiber-optic system gathers ambient light during the day, while the tritium takes over at night - so there are no batteries to fail or replace. Multi-coated optics deliver clear, high-contrast imaging across the full 36.80 ft @ 100 yds field of view, with a comfortable 1.50" eye relief that supports fast, both-eyes-open target acquisition.

The body is machined from forged aluminum and finished in matte Black Hardcoat Anodized for corrosion and wear resistance. Fully sealed, the optic is fogproof, shockproof, and waterproof, built to hold zero through hard use, rough handling, and recoil. Windage and elevation adjustments click at 2 per inch at 100 yards for precise, repeatable zeroing, while the compact 7.30" overall length and modest weight keep it right at home on a carbine, designated-marksman rifle, or any AR-pattern rifle.

Trusted by U.S. and allied troops and widely regarded as a gold-standard combat optic for the M4 and similar rifles, this Trijicon ACOG 4x32 is sold here brand new, factory fresh. The unit ships with the matching TA51 flattop mount, ready to drop onto any MIL-STD-1913 (Picatinny) rail for quick, secure installation out of the box.
