The PTG Pilot Bushing for Bolt Raceway Reamers, Receivers and Taps is a steel tapered pilot bushing. These bushing are designed for center tooling the action. To use the bushing, simply select the proper pilot bushing diameter that will enter the existing raceway. Next, insert the Raceway Reamer tool from the front end of the receiver. Begin your cut with one bushing on each side of the ejection port. As material is removed, the bushings, push out of the raceway and the tool "self-pilots" on it's major diameter. Once the raceway is cut to the tool diameter, the reamer (sold separately), can be used as a mandrel which is effectively match machined to the receiver.
