Featuring an innovative, low-profile design, Sightmark's LoPro Green Laser allows users to mount a high-power laser in front of a riflescope on a picatinny or Weaver rail without blocking the field-of-view. The Sightmark LoPro can also be mounted on the side of a quad rail for maximum efficiency. The laser is offset, clearing the front sight post to ensure perfectly centered aim of the laser. With 1 MOA-click value adjustments, the hand adjustable windage and elevation turrets allow the user to zero in the laser dot for close-range shooting. Visibility ranges approximately 50 yards in the daytime to more than 600 yards at night. Constructed of high-performance thermoplastic, the unit is corrosion resistant, weatherproof, shockproof, and features a matte black finish for tactical applications. Exceptionally reliable and durable, the device provides nearly 30 hours of continuous use with a single CR123 battery.
