Sightmark’s LoPro Green Laser Designator allows you to mount a high-power laser in front of a riflescope on a picatinny or Weaver rail without blocking your field of view. The laser is offset, clearing the front sight post to ensure perfectly centered aim of the laser. With a visibility of up to 600 yards at night, it’s the perfect accessory for precise tactical long-range shooting in low-light or nighttime conditions.
