Front sight tower clamps directly to a gas block with a topside accessory rail and provides a super-bright, green fiber optic dot for fast, easy-to-see sight pickup in all ambient light conditions. Push the rubber-sealed on/off button, and the integral battery-powered light source illuminates the extra-long, fiber optic rod so you are never left without a highly visible front sight, even at night. Front blade is easy to adjust for elevation. Lightweight aluminum base with dual protective ears attaches without gunsmithing to Picatinny or Weaver rail front gas blocks.
