Trijicon 100218 ACOG 4x32mm 223/5.56 BDC Illuminated Green Chevron Riflescope - Black Hardcoat Anodized

The Trijicon ACOG 4x32 (Advanced Combat Optical Gunsight) is the combat-proven fixed-power optic trusted by military, law enforcement, and serious civilian shooters. This TA31F-G configuration (item 100218) pairs fixed 4x magnification with a 32mm objective in a compact package finished in non-reflective black hardcoat anodized forged aluminum.

The dual-illuminated Green Chevron 223/5.56 BDC reticle is calibrated for the 223/5.56 cartridge. The bright green chevron tip provides fast, instinctive target acquisition at close quarters, while the bullet drop compensator ladder offers holdover points for longer shots. The width of the chevron at the base is 5.53 MOA, which works out to roughly 19 inches at 300 meters for quick silhouette range estimation. Illumination is fully battery-free: tritium lights the reticle at night and in low light, while the integrated fiber optic collector automatically brightens the reticle in daylight conditions.

Internally adjustable for zero, the ACOG delivers a generous 1.5" eye relief and a 36.8 ft field of view at 100 yards. Multi-coated optics provide a clear sight picture, and windage and elevation adjustments click in precise .25 MOA increments at 100 yards. The housing is fogproof, shockproof, and waterproof to handle hard field use and the recoil of duty carbine and rifle platforms. Overall length is 5.8" and weight is 15.1 oz with the included mount.

This listing includes the TA51 flattop mount, ready to attach to any standard MIL-STD-1913 Picatinny rail. The Trijicon 100218 ACOG 4x32 delivers combat-proven speed, accuracy, and reliability in a single rugged package.
