Boresight lasers provide the most convenient and accurate method for sighting in all types of rifles. Simply chamber the boresight like a regular bullet and a laser dot will project to show exactly where the rifle is aiming. Boresight lasers make it easy to sight in any scope without firing a single shot. Live fire is only needed to fine tune a weapon being sighted in order to compensate for inconsistencies, such as bullet drop due to distance. Perfect for hunters or competitive shooters, the boresight laser is sure to take the frustration out of sighting in almost any firearm. It’s easy to use and will quickly save both time and money by avoiding prolonged live fire tests at the range; use the extra ammo for honing those shooting skills and for the hunt.
