Night Stick SFL-11WL Features The Nightstick SFL-11WL Shotgun Forend Light replaces the factory forend on a Mossberg 500 590 590A1 or Shockwave with a one-piece body of heavy-duty glass-filled nylon and an over-molded rubber grip area. A high-efficiency deep parabolic reflector focuses the 1200 lumen LED into a tight beam that reaches out to 203 meters giving shooters a usable working light for identifying targets at distance. The light offers over an hour and a half of continuous runtime and its white LED is housed behind a 1.30 head diameter reflector for a concentrated far-throwing beam. Waterproof construction lets the SFL stand up to wet range days and outdoor use without concern for moisture intrusion. Ambidextrous push-button switches are positioned intuitively toward the front of the forend for fast activation by either hand and each button is surrounded by a raised bump guard that helps prevent accidental activation while racking the action. An ergonomic palm swell design improves grip during light activation and weapon manipulation under stress keeping the shotgun controllable during rapid fire or movement. The forend installs using Nightstick s included action tube nut wrench which removes the factory-installed castle nut and pump handle and an optional hand stop safety strap adds a secure retention point. Powered by two CR123 batteries with the option to upgrade to a rechargeable 18650 kit and backed by a limited lifetime warranty the SFL-11WL gives Mossberg shotgun owners a dedicated built-in weapon light.
