Sightmark Premium Laser Boresighter .270 Winchester Short Magnum Rifles 2x AG5 Batteries Brass Body SM39011 Details

The Sightmark Laser Boresight provides the most convenient and accurate method for sighting in rifles and shotguns of all types. Simply chamber the boresight like a regular bullet and a laser dot will show exactly where the rifle is aiming. It's easy to sight in any scope without firing a single shot. Live fire is only needed to fine tune the weapon being sighted in order to compensate for inconsistencies, such as bullet drop due to distance. Perfect for hunters, competitive shooters and law enforcement, the Sightmark Laser Boresight is sure to take the frustration out of sighting in almost any gun. 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. A lightweight carrying pouch protects the laser for convenient use in the field. The Sightmark Laser Boresight is available in several calibers and gages for use with all the most popular rifles and shotguns. Sightmark-Make Your Mark!
