Adapted from the battlefields, US Forces have begun improving this proven Trijicon ACOG scope by adding a small red dot sight on top for close encounter missions. Trijicon has now created a similar model for the public, the TA31-C-100550. The main Trijicon scope provides an illuminated reticle using fiber optics and tritium for bright aiming point in any light condition. The ranging reticle allows for bullet drop compensation out to 600 meters without any manual adjustments. A Trijicon RMR Type 2 sits on top with a 3.25 MOA aiming dot. Includes 3.25 MOA RMR Type 2, thumbscrew flattop adapter, LENSPEN, lanyard assembly for adjuster caps, Trijicon logo sticker, ACOG manual and warranty card.
