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. 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. Easy to use and quickly saves both time and money by avoiding prolonged live fire tests at the range. Comes with a lightweight carrying pouch for protection in the field.
