Three piece bushing set for the Steampunk Bolt Action kit. You only need the two smaller end bushings. The complex middle bushing is for use with the Victorian pen kit (not currently available through Bear Tooth Woods).
These bushings cannot be used for the 30 Caliber Bolt Action Rifle Pen kits or any other Bolt Action pen kits (i.e. American Eagle, Deer Hunter, Salute the Troops, and Statue of Liberty).
