This shotgun forend weapon light is a complete forend replacement for your 12 gauge MossbergA(R) 500/590/590A1 or Shockwave pump-action shotgun. Built from a one-piece body of heavy-duty glass-filled nylon with an over-molded rubber grip area, it features a super-bright LED rated at 1200 lumens with an hour and a half runtime. Designed around a high-efficiency deep parabolic reflector, the tightly focused beam has a 203-meter beam distance. The SFL forend features ambidextrous switches positioned intuitively towards the front for easy activation. Both buttons are surrounded by a small raised bump guard that helps prevent accidental activation while racking the action or laying it on its side. The light also features an ergonomic palm swell design to improve grip during light activation and weapon manipulation under stress. Each SFL comes with an optional hand stop/safety strap and Nightstick's SFL action tube nut wrench for removal of factory-installed castle nut and pump handle fore-end. Comes with two CR123 batteries, but can be upgraded to li-ion rechargeable with optional 18650-KIT. Limited lifetime warranty.
