It’s a light AND a sight! The NRA Hellfighter Underboss fits any rifle or handgun with a Picatinny rail. Quick-mount it in less than a second without placing your hand in front of the muzzle --- or it can be permanently screwed down. Built to withstand the excessive punishment of military combat, the Underboss delivers an incredibly bright, 150 lumen white beam. Its visible red laser weighs in at 635nm and packs the maximum output power allowed by law (this laser is visible in bright sunlight up to 400 yards, and up to 2,000 yards in the dark). Use the light and the laser simultaneously, or choose to utilize just one at a time. Momentary, touch-on, lock-on and remote modes are selectable, and the Underboss comes complete with a pressure-sensitive remote flag switch. NRA logo is printed on both sides of the housing. Body: Aramid fiber composite housing with steel fastening points. Size: 4” x 1½” x 2”. Laser dot size: 1 MOA. Runs on 2 included Lithium 123 batteries. Includes hex key for windage/elevation adjustment. Assembled in USA using foreign and domestic parts.
