The Bushnell Professional Bore Sighter is the finest boresight collimator available. We use it in our RingTrue™ rifle scope installation kits. It includes a deluxe carrying case.

The Bushnell Professional Bore Sighter includes a set of three adjustable arbors, for use with nearly any caliber firearm between .22 and .45 caliber, and a .17 caliber spud. When maintained and used properly, the arbors are reproducible within +/-0.5 MOA. The objective lens provides a wide field of view. This boresight collimator works with all the precision spuds from Alley Supply.

The uses for this boresight collimator are endless:
–   Optical zeroing
–   Boresight calibration of the rings to the bore
–   Changing scopes without losing zero
–   Checking if a floated stock changes POI

The collimator grid is has a pattern of 21 horizontal and vertical lines, separated by 4 IPHY. This boresight collimator does not include a level.

Accuracy: The collimator grid is centered to within 5 MOA of the bore axis from the factory. Lately the boresight error has been ~3 MOA in the collimators we’ve inspected. For even greater accuracy, purchase our Boresight Collimator Calibration Service for an extra $20 (see options above).
