Easy-to-use, self-contained bore sighting system fits in the

chamber of your rifle and projects a powerful red laser beam aligned with the bore axis for sighting to the point-of-aim without firing a shot.


Works with scopes, holographic red dot sights and iron sights. Durable, machined brass housing looks like a cartridge case but contains the entire laser system and batteries. Insert the batteries and screw the cap on the housing to turn on the laser, 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. Adjust the windage and elevation of the scope or sights so point-of-aim is zeroed in.
