Bushnell 740001C Magnetic Boresighter

This Boresighter saves time and ammunition by helping you align the scope's crosshairs with the gun's bore before you even get to the range. Works with all scopes. The magnet eliminates the need for arbors. Covered by limited lifetime warranty. Notes: Etched glass reticle Needs no arbors or extra equipment Uses a built in magnet to attach to the muzzle of the gun Requires no Batteries Procedure: (See Product Instructions for Full Procedure) Position the boresighter roughly the same height as the centerline of the objective end of the scope mounted on the gun Look through the scope & by rotating the boresighter slightly, align the reticle of the scope with the vertical and horizontal lines of the boresigher's target grid, visible through the scope. Using the scope's windage & elevation adjustments, align the scope's reticle with the centering dot of the boresighter's target grid. Remove the boresighter, the scope should be "on the paper."
