Barrel Cutting

Many people cut down longer barrels to fit into smaller weapons. It is a popular practice that saves buying a whole new set of barrels each time a new weapon is purchased. However, unless done properly it can render a perfectly decent barrel useless. A general guide is set out below, but anyone attempting to cut a barrel does so at their own risk.

Tools Needed

  • Decent junior hacksaw, with fine (> 30 TPI) blade, preferably hardened steel
  • A bench vice or similar apparatus to hold the barrel, padded if possible
  • Large (~ 1/2") drill bit
  • Small (~ 1/16 - 1/8") round modellers file
  • Medium (~ 1/2") flat file
  • Barrel Cleaner and relevant oiled cloth

Procedure

  1. Measure and mark the barrel to where it needs to be cut.
  2. Measure a second and third time, ensure you are not cutting the wrong end of the barrel.
  3. Mount the barrel in the vice (use some cloth round it if it's not padded to avoid scratching), with the point of cutting just exposed so as to minimize bending.
  4. Carefully cut off the excess with the hacksaw.
  5. Use the flat file to ensure you have a perfectly square end, and remove the outer rough edge.
  6. Use the file on the inside of the newly cut end to remove the inner rough edge.
  7. By hand, use the large drill bit to de-burr the inside of the barrel, making it super smooth.
  8. Clean the barrel by pushing the cloth through with the cleaning rod from the hop end to the new muzzle end.
