The popular Streamlight ProTac series continues to impress with the addition of rail mounted lights specifically designed for long rifles. The lightweight ProTac Rail Mount 1 is a medium output light that produces 350 lumens on a high setting, with the use of one CR123 battery. The lower setting provides an incredible 14 hours and 30 minutes run time, for maximum defense in low light. This resilient long gun light is constructed from durable, anodized aircraft aluminum and features an integral M1913 Picatinny dedicated fixed-mount that attaches easily to a rifle rail without the use of tools. It is also equipped with a pressure pad on/off activation system that allows officers to light up temporarily or go full on. And the innovative Rail Mount 1 features Streamlight's Dual Fuel Design, which can run on a lithium battery or an easy-to-find AA alkaline battery. The engineered optic produces a concentrated beam for extreme brightness and one handed operation for convenience. Having a weapon mounted light is an incredible advantage during low light engagements and the ProTac Rail Mount 1 is a shining example of the excellent engineering Streamlight offers to help you conquer the darkness.
