Nightstick SFL11WL Forend Light - 1200 Lumens, Over-Molded Grip, Fits Mossberg 500/590/590A1/Shockwave

The Nightstick SFL11WL forend light is a purpose-built 1200-lumen weapon light designed as a complete forend replacement for Mossberg 500, 590, 590A1, and Shockwave pump-action shotguns. If you're running a home-defense or tactical shotgun and need reliable illumination for low-light situations, this light eliminates the need for clunky add-ons by integrating seamlessly into your gun's natural handling. Built from heavy-duty, glass-filled nylon with a substantial over-molded rubber grip section, it's engineered to withstand the recoil and abuse shotguns deliver while keeping your support hand comfortable and in control.

The 1200-lumen output is driven by a high-efficiency deep parabolic reflector that produces a tightly focused beam capable of reaching out to 203 meters—plenty of reach for identifying threats beyond arm's length. With an hour and a half of runtime per battery set, the SFL11WL keeps working when you need it most. Ambidextrous controls let you activate the light from either side, and each button is ringed with a raised bump guard to prevent accidental activation. The ergonomic palm swell and available hand stop/safety strap add an extra measure of control and security, critical when you're maneuvering a shotgun in dim conditions.

The light ships with two CR123 batteries to get you running immediately. If you prefer the flexibility of recharging, Bayco offers an optional 18650 rechargeable li-ion upgrade kit. The package also includes Nightstick's SFL action tube nut wrench, so you have the right tool to install or remove the forend cleanly. This is a no-compromise lighting solution for anyone serious about shotgun preparedness.
