Night Fision Night Sight Set Orange Front Square Notch Rear FN 509 Pistol Accessory

Night Fision’s patented injection molded sleeve design securely holds tritium vials using ballistic materials. This night sight set carries more tritium than typical night sights and features a domed lens engineered to create a crisp defined glow. The sights are CNC machined from high quality steel and finished with Black Nitride coating for improved wear and corrosion resistance. Built in the USA with Swiss Tritium, these are among the brightest tritium night sights available. The domed lens collimates tritium rays for a sharper sight picture. Installation by a gunsmith is recommended.
