The Nightstick Tactical Long Gun Light Kit provides everything necessary to add a high-power tactical light to any long gun that has a Picatinny or Weaver rail. At the heart of the kit is the Nightstick TAC-300B polymer tactical light rated at 180 lumens. Combined with a high-efficiency deep parabolic reflector, the beam on the TAC-300B is distance rated at 190 meters perfect for long-distance target acquisitions. With a wide secondary halo of light, the TAC-300B is equally effective in CQB situations. With its momentary on/off design, the Remote Pressure Switch assures the operator of complete control over the full power of the light. The light is made from a glass-filled nylon polymer. This kit includes the TAC-300B tactical light, the standard tail switch with momentary or constant-on functionality, the removable pocket clip, the Remote Pressure Switch, the Quad Lock Mount, the self-adhesive Velcro strip, an alcohol pad for surface prep and two CR-123 Lithium Batteries.
