Compact, 4X magnification scope features a bright, red Chevron reticle that is lit by both fiber optics and tritium for a vivid sight picture at distances up to 800 meters. Uses the Bindon Aiming concept (BAC) for excellent, both-eyes-open, target acquisition. Chevron reticle looks like an upside down “V”; provides similar benefits of triangle reticles without covering up as much of the target. Sight tunnel retains use of iron sights. Mounts to Colt, military-style, flat top rails.
