The TL-Racker replaces the forend on your shotgun for positive identification of targets and enhanced safety. The light delivers 1,000 lumens of bright white light with a concentrated beam and peripheral ring to help maintain situational awareness while illuminating your target. Integrated pressure pads on both sides of the forend enable easy access for left and right-handed users to switch between momentary and constant-on activation modes. The forend is made from an impact-resistant nylon polymer with a deeply ribbed textured grip for secure handling. This light is IPX7 waterproof, allowing submersion up to 1m of water for 30 minutes.Compatible with most 12 gauge 870s except the Remington 870 Express Supermag.
