• Factory-aligned laser beam aligns sight picture with point of projection

The SME Sight-Rite Chamber Cartridge Laser Bore Sighter in 20 gauge is a practical zeroing aid for 20-bore shotgun owners fitting new sights, red-dot optics or slug scopes. The bore sighter is a precision-machined calibre-specific casing that seats directly into the 20-gauge chamber just as a shell would, with no adaptors or cleaning rods required. A high-performance laser beam is projected from the muzzle end, enabling the shooter to align the sight picture with the laser's point of projection. The laser comes factory-aligned and batteries are included, so it is ready to use out of the box. Using a bore sighter before a sighting-in session gets the point of impact on target faster, reducing wasted ammunition and frustration at the pattern plate or slug range. A straightforward, effective tool for any 20-gauge shooter setting up iron sights or an optic on a slug or specialist shotgun.
