Steiner brings battle-proven durability and mil-spec ruggedness to pistol red dots with the NEW MPS (Micro Pistol Sight). All-metal construction and enhanced sidewalls completely seal in the emitter. A recessed window with a metal hood blocks objects from reaching the front lens making this one of the toughest pistol sights ever created. At 2.05 oz, the Micro Pistol Sight is compact and lightweight offering Steiner quality glass and a robust feature set including 8 brightness levels, and 13,000 hours of battery life.
