The FT Bullseye Sight is one of the most innovative tritium/fiber optic sights ever developed by Meprolight, and delivers a fast and instinctive aiming solution for pistols. Its unique design removes the need for traditional front and rear sights (which also removes a snag-hazard), and makes target acquisition faster. The aiming point is composed of a ring and a center dot, to use the FT Bullseye, align the dot in the center of the ring, when the dot is centered in the ring the weapon is on target. When in broad daylight, the FT Bullseye is powered by fiber optics to provide ultra-bright illumination, while tritium illuminates the sight in the dark. Transition between aiming in bright and low-light conditions is seamless, and the tritium/fiber optic system means no batteries are needed.
