A finish reamer designed to remove the last few thousandths from a "short chambered" barrel to properly headspace the rifle. The reamer is inserted into the chamber, allowing the bolt to push on the back of the reamer. A drive rod is threaded into the reamer, inserted from the muzzle and turned from the muzzle end. Finish ream the chamber until the bolt lugs drop-in for perfect headspace. Insert the reamer into the pre or short chamber. Make sure the bushing is on the end of the reamer then screw the drive rod into the pilot of the headspace cutter after carefully slipping the drive rod down the barrel. Rotate the cutter with foreward pressure applied to the bolt.
