Trijicon 100156 ACOG 3.5x35mm Green Horseshoe .223/5.56 BDC Riflescope - Black Hardcoat Anodized

The Trijicon 100156 ACOG is a fixed-power combat riflescope built around a 3.5x magnification and a 35mm objective lens. Part of the battle-proven TA11H-G family, this ACOG pairs an illuminated Green Horseshoe .223/5.56 BDC reticle with a Black Hardcoat Anodized housing, delivering a rugged aiming system for the M16 and AR-15 platform chambered in .223 Remington / 5.56 NATO. The included thumbscrew mount allows fast, tool-free attachment to a flattop receiver.

The reticle is dual illuminated by a combination of tritium and fiber optics, producing a self-luminous aiming point that works in any light condition without the need for batteries. The Green Horseshoe pattern snaps onto targets quickly for close-quarters work, while the .223/5.56 BDC ladder provides precise holdovers out to 600 meters. Adjustment is 3 clicks per inch @ 100 yds for tactile, repeatable zeroing.

Optical performance comes from multi-coated lenses that maximize light transmission and contrast with zero distortion. The scope is fogproof, shockproof, and waterproof, dry-nitrogen filled to seal out the elements and built to handle punishing recoil. At 8" long and 14 oz, with 2.40" eye relief and a 28.9 ft @ 100 yds field of view, the 3.5x35 ACOG is a compact, rugged optic designed for military and tactical applications.
