Trijicon 100226 ACOG 4x32mm Illuminated Red Chevron Riflescope - Black Hardcoat Anodized

The Trijicon 100226 ACOG (Advanced Combat Optical Gunsight) is a battle-proven fixed-power 4x32mm riflescope built to USMC specification for the M16A4 weapon system. This is the TA31RCO-A4CP configuration featuring an illuminated red chevron reticle calibrated for .223 Remington / 5.56 NATO, offering lightning-fast target acquisition at close combat ranges with quick hold references out to extended distances.

The ACOG's signature dual-illumination reticle uses a combination of tritium and fiber optics to keep the aiming point lit in any lighting condition - no batteries required. The fiber optic system gathers ambient light during daylight while the tritium takes over in low light, so the chevron is always visible without switches or power concerns. The bold red chevron provides an unmistakable aiming reference ideal for both-eyes-open engagement.

Optically, the ACOG delivers fixed 4x magnification through a 32mm objective with multi-coated lenses for excellent light transmission and clarity. The scope offers a generous 36.80 ft @ 100 yds field of view, 1.50 inches of eye relief, and tactile .25 MOA per-click adjustments at 100 yards. Total length is 5.80 inches and the optic weighs 15.80 ounces.

Built for hard service, the ACOG features a forged aluminum housing finished in black hardcoat anodizing for outstanding corrosion and wear resistance. It is fogproof, shockproof, and waterproof to withstand the harshest combat and field conditions - the same optic specified by the United States Marine Corps for the M16A4 weapon system.
