Meprolight USA 631013108 FT Bullseye Rear Sight Green Tritium FO/Black Frame Compatible w/Glock Gen 1-5 (Except MOS), Dovetail Mount

Born from an engineering masterpiece, the Mepro FT Bullseye family, the worlds smallest and brightest reflex-style optic for pistols, is so intuitive it will make you a much faster and accurate marksman. The low height over bore single-night-sight design is powered by fiber optics to master the day, while premium-grade tritium handles low-light as well as the darkest conditions. The Mepro FT Bullseye Sight was designed to fit most standard holster designs with no adjustments allowing the shooter to just install the sight to the slide and hit the range. Fits All Glock Models except MOS.
