Bolt Action Pen Kit Bushing Set

Set of bushings for the PSI 30 Caliper, PSI Mini 30 Caliper, and PSI Deer Hunter Bolt Action Pen Kits.

To use, simply mount the blanks between the bushings (following the kit instructions) onto a 7mm pen mandrel. Turn the blanks down to match the bushing diameter, leaving a little extra material for final sanding and finishing.
