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

The Trijicon ACOG (model TA31-CH, part number 100233) is a fixed 4x32mm combat riflescope engineered for hard use on .223/5.56 carbines and rifles. This battle-proven optic features a dual-illuminated red crosshair .223/5.56 BDC reticle lit by a combination of tritium and fiber optics - no batteries required - providing a bright aiming point at any light level from bright daylight to complete darkness.

At just 5.80" long and 15.10 oz, the ACOG is compact and light enough to preserve a balanced rifle platform while delivering 36.80 ft of field of view at 100 yards and 1.50" of eye relief. The reticle's BDC (Bullet Drop Compensating) ladder is calibrated for 5.56/.223 flattop rifles out to 800 meters, giving the shooter a fast, intuitive hold at varying ranges without dialing turrets. Adjustments click at 2 clicks per inch at 100 yards.

Built around a rugged housing finished in black hardcoat anodized, the scope is fogproof, shockproof, and waterproof to handle recoil, rough field use, and adverse weather. Multi-coated optics maximize light transmission and contrast for a crisp aiming picture. The TA31-CH ships with the TA51 mount for flattop Picatinny rails, ready to bolt directly to an AR-15 or M4-pattern upper receiver.
