Trijicon 100144 ACOG 3.5x35mm Illuminated Green Chevron .308/7.62 BDC Riflescope - Black Hardcoat Anodized

The Trijicon 100144 ACOG is a fixed-power combat riflescope built around Trijicon's battle-proven Advanced Combat Optical Gunsight platform. This 3.5x35mm configuration pairs a compact 35mm objective with an illuminated green chevron .308/7.62 BDC reticle, giving shooters a fast, intuitive aiming point calibrated for .308/7.62 flat-top rifles out to 800 meters.

The dual-illumination reticle gathers ambient light through fiber optics for bright-daylight use and switches to tritium for low/no-light conditions, with no batteries required. Adjustment is positive and precise at 3 clicks per inch at 100 yards, and the optic provides 2.4" of eye relief with a generous 28.9 ft field of view at 100 yards for rapid target acquisition.

Optics are multi-coated for clarity and light transmission, and the housing is finished in black hardcoat anodized aluminum for corrosion resistance in harsh environments. At 8" long and 14 oz, the ACOG adds minimal bulk to a rifle platform while delivering the legendary durability Trijicon is known for.

Built to Trijicon's combat-tough standards, this ACOG is fogproof, shockproof, and waterproof, proven to withstand recoil from .22 LR through .50 BMG and to pass U.S. military drop test requirements. It ships with the TA51 mount ready for flat-top AR-pattern and similar rifles.
