Trijicon’s LED ACOG offers user-selectable brightness controls. Users can select from six adjustable brightness levels with an “off” between each setting, allowing the operator to determine how much to illuminate the reticle – even in transitional lighting. Powered by a single AA battery, the LED ACOG can run for over 12,000 continuous hours (on setting #4). The body has been optimized by moving the RMR mount forward to maximize its performance in conjunction with the ACOG. Includes a thumbscrew flattop adaptor, AA battery, LENSPEN, lanyard assembly for adjuster caps and battery cap, Trijicon logo sticker, ACOG manual and warranty card.
