Nightstick SFL-11GL Features The Nightstick SFL-11GL replaces the factory forend on a compatible Mossberg shotgun with a one-piece glass-filled nylon housing that integrates a 1200 lumen LED and a 520 nanometer green laser into a single unit. A deep parabolic reflector focuses the beam for a rated distance of 203 meters giving the shooter a sharp usable light source for identifying threats at range. The laser and light can be run independently or together in constant-on or momentary modes so the operator can match output to the situation. Ambidextrous switches are positioned toward the front of the forend for intuitive activation from either hand under stress. A raised bump guard surrounds both buttons to help prevent accidental activation while racking the action or setting the shotgun down and an ergonomic palm swell improves grip during activation and manipulation. The unit is IPX-7 waterproof and built to resist impact and chemical exposure backed by Nightstick s limited lifetime warranty. It ships with two CR123A batteries installed a hand stop safety strap and the SFL action tube nut wrench needed to remove the factory castle nut during installation. The Nightstick SFL-11GL can also be upgraded to a rechargeable li-ion battery with Nightstick s optional 18650 kit.
