Constructed from tough T6 aluminum, the Laser Bore sighter comes in a sleek red finish and works great on any weapon with at least three inches of barrel length. The Universal Laser Bore sighter makes sight-in sessions a breeze for scopes, lasers or iron sights on any firearm from .22 to .50 caliber with included adapters.
