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