Bushnell. Lightweight and easy to use, the Laser Boresighter comes with 5 arbors that are compatible with .22 to .50 caliber firearms. Simply install three LR44 batteries, select the correct arbor for the firearm, thread the Laser Boresighter into the barrel and turn the laser on. Orienting your firearm toward a vertical surface, the laser dot will indicate exactly where the barrel is pointed.
