The Accudot™ 300 Laser Bore Sight by Sightmark® provides a convenient and accurate method for sighting in rifles of all types. Simply chamber the bore sight like a regular bullet and a laser dot will show exactly where the rifle is aiming. It’s easy to use and will save both time and money by avoiding prolonged live fire tests at the range. A lightweight carrying pouch protects the laser for convenient use in the field.
