Advanced boresighting system projects a bright red laser dot precisely aligned with the centerline of the bore for sighting in scopes, red dots, and “iron” sights. quickly and easily. Just insert the boresighter into the chamber, close the action, and aim at a target 25 yards away. Adjust windage and elevation of scope or sights to align with the laser dot on the target. Permanently calibrated at the factory to project a 1.5" diameter dot at 100 yards. Separate, interchangeable “arbors” slide over the basic laser unit for sighting in other calibers without buying a whole new boresighter—a substantial cost savings. .223 boresighter accepts arbors for a variety of rifle calibers and 12 gauge shotgun; .30 Carbine boresighter accepts arbors for .38 Special/.357 Magnum and .45 Long Colt. Precision machined brass housing won’t mar the chamber and helps ensure a tight fit. Boresighter includes instructions and nylon storage case with room for 9 arbors; arbors sold separately.
