The Nightstick Xtreme Lumens 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-460XL Xtreme Lumens metal tactical light rated at 800 lumens. Combined with a high-efficiency deep parabolic reflector, the beam on the TAC-460XL is distance rated at 205 meters…perfect for long-distance target acquisitions.
