Our patented injection-molded sleeve design securely holds our tritium vials in place using high-performance ballistic materials, ensuring durability and reliability. Night Fision night sights contain more tritium than the average night sight available, providing enhanced brightness and visibility in low-light conditions. Additionally, each sight features a domed lens specifically engineered to create a crisp, defined glow, facilitating quick and accurate target acquisition when it matters most. With Night Fision, you can count on superior performance and clarity in any environment.
