The Sightmark 300 Blackout/300 AAC Boresight is the first boresight specifically dedicated to 300 BLK weapons. The Sightmark 300 Blackout Boresight provides the best, most efficient method for sighting in any 300 BLK weapon system. This boresight gets bullets on paper at 50 yards by helping the shooter sight the weapon to the point of impact. The laser is secured by screws that are set into a brass casing, offering precision accuracy with minimal ammunition. The brass casing makes the 300 Blackout Boresight exceptionally durable while preventing the boresight from damaging the chamber of the weapon.
Simply chamber the boresight like a regular bullet and a laser dot will appear where the weapon is aiming. Any person can sight in any scope without firing a single shot. Live fire is only needed to fine tune the weapon for bullet drop and windage compensation. Perfect for hunters, competitive shooters or any gun enthusiast, the 300 Blackout Boresight is sure to take the frustration out of sighting in a 300 BLK weapon. It’s easy to use and saves 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. The boresight comes with a nylon carrying case, making it easy to pack and travel with.
