This is one of the simplest bore sighters you will ever use. Simply chamber the bore sight like a normal cartridge and a laser will shoot out of the barrel showing exactly where your rifle or shotgun is aiming. This will save time and ammunition as only a few shots will have to be fired for fine tuning.
