Trijicon
The Trijicon ACOG 4x32 TA31RCO-A4CP is the Rifle Combat Optic - the exact ACOG configuration that the United States Marine Corps adopted as its standard issue optic for the M16A4 service rifle. The USMC RCO Reticle configuration is the most operationally validated ACOG variant in history, carried and deployed by Marine infantrymen in combat operations worldwide, and proven through the most demanding real-world operational use that any rifle optic has ever seen.
The RCO Scope reticle TA31RCO-A4CP is the specific reticle configuration developed for and adopted by the Marine Corps - the chevron-based reticle with bullet drop compensation out to 600 meters that Marine riflemen have trained with and trusted in combat without any manual turret adjustments required between engagement distances. For shooters who want the exact reticle configuration that USMC service members carry, the Trijicon RCO TA31RCO-A4CP is the authentic configuration - not a civilian approximation but the actual adopted optic.
The ACOG 4x32 TA31RCO-A4CP 4x magnification and 32mm objective deliver the target-identification capability and sight-picture quality that medium-range rifle engagement demands - the magnification level that US military and law enforcement professionals have standardized on more widely than any other fixed-power combat optic configuration. Battery-free fiber-optic and tritium dual illumination keep the RCO Scope Reticle lit in any lighting condition, automatically and without batteries.
The Trijicon ACOG Scope TA31RCO-A4CP carries the full weight of the most combat-proven magnified optic in history — over one million produced and deployed by US Special Operations Forces, the Marine Corps, and law enforcement agencies across the country.
Trijicon ACOG riflescopes come in the following magnification levels:
1.5x16, 1.5x24, 2x20, 3x24, 3x30, 3.5x55, 4x32, 5.5x50, and 6x48.
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. With a wide array of magnification levels, reticle designs, and reticle colors available — there truly is an ACOG for every mission.
Trijicon ACOG riflescopes come in the following magnification levels:
1.5x16, 1.5x24, 2x20, 3x24, 3x30, 3.5x55, 4x32, 5.5x50, and 6x48.
