Bushnell Professional Boresighter With Arbor Kit

The Bushnell Professional Boresighter With Arbor Kit is a precision optical alignment tool designed to help shooters quickly align a riflescope or adjustable iron sights with the bore of a rifle or handgun. By providing a clear graduated reference grid, the boresighter allows windage and elevation adjustments to be made before live firing, helping place the first test shots on paper while reducing the time and ammunition required to achieve a final zero.

The kit includes a professional optical boresighter and a selection of arbors designed to fit a wide range of barrel diameters. The expandable arbors secure the unit firmly inside the bore and cover common calibres from .22 to .45, while the included fixed arbor accommodates .17 calibre firearms. The graduated grid can also be used to record a firearm’s established sight setting, making it easier to check whether a scope has shifted after transport or storage. Supplied in a protective storage case, the Bushnell Professional Boresighter With Arbor Kit is a practical addition to any shooting, hunting or gunsmithing setup.
