Night Fision’s patented injection molded sleeve design secures their tritium vials in place using ballistic materials. Night Fision night sights contain more tritium than comparable night sights and feature a domed lens engineered to produce a crisp, defined glow.
Features include the brightest tritium night sights available on the market. The domed lens collimates tritium rays for a sharper sight picture. Construction uses CNC machined high quality steel with Black Nitride coating to enhance wear and corrosion resistance. Gunsmith installation is recommended. Built in the USA with Swiss Tritium, these sights are designed for the FN 509 Pistol with an orange front sight and U notch rear sight configuration.
