The Leupold Mark 4 CQ/T is ready and able to handle the variety of close-contact situations common to both law enforcement and the military. It features a true 1x setting so it functions as your non-magnifying, illuminated sight at extremely close range. 2x or 3x settings give you the additional power to accurately engage targets at medium ranges. The Leupold Circle Dot reticle with ten illumination settings is a bold aiming point and also provides range estimation. Night-vision device compatible. Attach accessories using the integrated MIL-STD-1913 rail mount cross-slots. ½ MOA adjustments for windage and elevation. One AA battery powers up to 600 plus hours at medium setting.
