Abstract From the Canadian patent
Abstract of the Disclosure A conversion plug that is configured to be removably inserted into the breech of a breech-loading firearm, converting the firearm to one of a muzzleloading type. The plug is provided with a primerreceiving chamber at one end and a series of passages that communicate the chamber to a region proximate the other end. The primer-receiving chamber is adapted to receive a percussion-type primer detonation, of which generates ignition products which are communicated via the series of passages to a main powder charge situated at the interior end of the plug to cause combution of said charge and propel a projectile from the firearm.
