    The TA31RCO is an Advanced Combat Optical Gun sight (ACOG) designed for the M16A4 Weapon system (20" barrel). It incorporates dual illumination technology using a combination of fiber optics and self- luminous tritium. This allows the aiming point to always be illuminated without the use of batteries. The Tritium illuminates the aiming point in total darkness, and the fiber optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness. Designed to the exact specifications of the United States Marine Corps, the unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters utilizing the Bullet Drop Compensator.

    The TA31RCO-A4CP also includes:

    - 1 Thumbscrew Flattop Adapter (TA51)
    - 1 RCO 4x32 ACOG Pouch (TA86)

    The Best Rifle Optic On The Market

    I am proud to own this fine piece of equipment. I am very confident using this on the range and I would consider no other scope to take into combat. I was trianed by the best marksmanship program in the world using this RCO, the United States Marine Corps. This optic not only has deadly precision at 800 meters, but is also ideal for short ranges like 25 meters or less. It allows for both eyes open while shooting, giving you complete visibility. This scope is also very durable, making the most reliable in the world. If you own an AR-15 or any other M16 style weapons, it isn't complete without the Trijicon Acog 4X32 Scope.
