Bushnell 743333 Delux Banner Boresighter, .22 to .45 Caliber

The Bushnell Professional Boresighter is for quickly adjusting scope or iron sights to align with the rifle or handgun barrel. The boresighter will put sighting-in test shots on the paper, requiring only minor expenditure of time and ammunition by test firing to achieve pin-point zero at a given distance. Because of the many variables involved in both ammunition and the firearm itself, final sighting in must be done by actual live firing. Includes: Boresighter; .17" arbor; .22-.27" arbor; 7mm-.35" arbor; .35-.45" arbor; carry case and paper instructions.
