Night Fision Optics Ready Stealth Series Sights Features The Night Fision Optics Ready Stealth Series Sights are CNC machined from high quality steel giving the set the strength and precision needed for a reliable co-witness with a slide-mounted optic. Where many competitors rely on aluminum sleeves and painted-on white rings around the tritium vial Night Fision uses a patented injection molded sleeve design that holds the tritium securely in place while creating a brighter more durable ring. This design called The Perfect Dot delivers maximum visibility in both daylight and low-light conditions. A Black Nitride coating further improves the set s wear and corrosion resistance over standard finishes. This set is built specifically for Glock pistols cut for the MOS pattern at a height compatible with the RMR 507C and 508T optic footprints ensuring proper co-witness alignment rather than a sight height that sits too low or high. Fitting a wide range of popular Glock MOS models including the 17 19 45 and 47 the set gives owners of those pistols a direct upgrade path. The blade height falls between .330 and .353 inches dialed in specifically for optic-equipped slides. For Glock MOS owners who want a durable bright properly height-matched sight set this Night Fision Stealth Series is a proven choice.
