12 Gauge Bore Sighter

This easy-to-use, self-contained 12ga bore sighting system fits in the breech of your shotgun and projects a powerful red laser beam aligned with the bore axis for sighting to the point-of-aim without firing a shot. Simply insert the batteries and screw the cap on the boresighter housing to turn the laser on, remove the batteries to turn off. Insert the entire assembly into the chamber, gently close the action, and aim at a target 20-30 yards away.
