Abstract
A bore sight () is provided that can be used with many calibers of firearms () to align optical devices such as rifle scopes. The bore sight () has a housing () with a spring loaded arbor () extending from one end thereof. The arbor () has a tapered face () varying in diameter in a range including popular calibers, such as .17 to .50 caliber. The arbor () is inserted in the end () of the barrel () as far as the caliber of the barrel () permits. The arbor () then starts retracting into the housing () against the spring force to allow the magnetic alignment face () of the housing to move into contact with the end () of the barrel to align the bore sight () and laser () with the bore ().
