Trijicon 100156 ACOG 3.5x 35mm Obj 28.90 ft @ 100 yds FOV Matte Black Finish Dual Illuminated Green Horseshoe 223 Ballistic

Trijicon's ACOG (Advanced Combat Optical Gunsight) is a fixed power, compact riflescope with an illuminated reticle pattern for use in bright to low/no light with legendary durability and reliability. Every feature of its design was chosen for a single purpose, to provide increased hit potential in all lighting conditions. Fewer moving parts than a variable optic equals more durability, and the forged 7075-T6 aircraft-aluminum-alloy housing provides for a nearly indestructible sighting system. M
