4.6mm tall spacer ring for 1.5" OD plunger tubes

Use this spacer to prevent plunger tubes from wiggling back and forth. Works on Breacher's magazine tube and others too. The spacer is 4.6mm tall. Scale the vertical direction in your slicer to make this fit your exact needs if necessary. When used on Breacher's magazine tube, make sure to put this on the FRONT of the tube. AKA, this spacer ring goes in the muzzle, so it forces the mag tube backwards more.
