Abstract From the Canadian patent

The outer end of the rod is recessed from the muzzle end of the barrel and is tapped and threaded. A key threads into the rod and may be pulled outwardly to remove the rod from the gun barrel.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
