With over one million produced, Trijicon’s Advanced Combat Optical Gunsight, better known as the ACOG has become iconic in the realm of combat optics — and for good reason, the ACOG has an unquestioned reputation for quality and reliability. The Trijicon ACOG is the official medium range weapon sight for both U. S. Special Operations Forces and the Marine Corps as well as being the optic of choice for law enforcement agencies across the country. What sets the ACOG apart from the pack is what it offers to its users, increased hit potential regardless of light conditions. This is due to the tritium/fiber optic illuminated reticle found in most Trijicon ACOG riflescopes, this automatically adjusts illumination of the reticle based on available light. As part of their 2022 lineup, Trijicon is now producing ACOG Scopes with the new Q-LOC Quick Release Mount. This innovative mounting system utilizes a proprietary spring-loaded attachment mechanism that allows for fast one-handed mounting, and allows the ACOG to be attached/removed without the need to re-zero the optic.
