The Trijicon ACOG (Advanced Combat Optical Gunsight) is a fixed power, compact riflescope with an illuminated reticle pattern for use in bright to low/no light. The ACOG is designed to be extremely durable and reliable. Combining traditional, precise distance marksmanship with CQB speed, many variants include a bullet drop compensated (BDC) reticle. Every feature of its design was chosen for a single purpose: to provide increased hit potential in all lighting conditions.

The chevron reticle is designed to be zeroed using the tip at 100 meters. The width of the chevron at the base is 5.53 MOA which is 19 in. at 300 meters. This allows range estimation for silhouette targets. Features dual illumination (Fiber optics provides daylight illumination and tritium illuminates reticle at night). The ranging reticle is calibrated for 5.56(.223 cal) flattop rifles out to 800 meters.

This mount fits all VCOG’s, the 1×42 Reflex (with ACOG base), and the 3.5x, 4x, and 5.5x ACOG’s. The AC12033 quick release mount utilizes a single lever system. It features the patented BLAC lever system which requires no manual adjustments to attain a proper, rock solid engagement on a 1913 picatinny rail.
