The Mepro FT Bullseye sight is the fastest, brightest, and most intuitive tritium fiber optic sights we’ve ever built. This low-profile single-night-sight design is powered by fiber optics to master the day, while premium-grade tritium handles even the darkest blackout conditions. Aligning with a single central point of focus, the Mepro FT Bullseye has the feel of a red dot sight. These Meprolight night sights are drop- and shockproof, built for endless rounds under heavy recoil, and make an excellent upgrade sight to pistols we service like Smith & Wesson, Springfield, IWI, Glock, and others. Its ultralight, snag-free design is easy to draw and gives you instinctive aiming under pressure.
