The Bushnell Professional Boresighter is an essential tool for quickly adjusting scope or iron sights to align with the rifle or handgun barrel. Correct use of This 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.
