Product Description The Night Fision Optics Ready Stealth (ORS) Night Sights are purpose-built for shooters who run slide-mounted red dot optics on their Glock 17, 19, 34, 45, 47, or 22. Engineered to provide a lower 1/3 co-witness position, these sights work seamlessly alongside the Holosun 507K, Trijicon RMR, and other similar-height optics. The ORS profile is specifically designed to obscure as little of the optic window as possible while still enabling reliable three-dot alignment when needed. The front sight features a high-visibility Yellow daylight-fluorescing ring surrounding a self-illuminating Tritium insert, delivering an exceptionally clear and fast sight picture under virtually any lighting condition. Night Fision uses 30% more Tritium than most competing sights, ensuring maximum brightness and longevity. The steel sight bodies are Nitride coated for superior durability and corrosion resistance, and Night Fision backs their Tritium inserts with an industry-leading 16-Year Brightness Guarantee.
