Abstract: A muzzle-loading firearm is disclosed. In the preferred embodiment, the muzzle-loading firearm includes a receiver having a locking mechanism; a barrel having a breech end, a bore and a muzzle end; a primer carrier for transporting a primer to the breech end of the barrel prior to firing and for extracting the primer from the breech end of the barrel after firing; and a breech plug in the breech end of the barrel, wherein the breech plug receives the primer from the primer carrier. In the preferred embodiment, the primer carrier includes a horseshoe-shaped primer holder attached to the locking mechanism.

Abstract: An improved muzzle-loading firearm which is achieved by modifying the design of the breech plug to include a replaceable aperture adjacent to the firing chamber which can be easily replaced if damaged beyond repair. In the preferred embodiment, the breech plug is adapted to receive an ejectable firing module which permits loading of the firearm as a muzzle-loader, while also permitting the firing module to be inserted and ejected like a cartridge in a conventional breech loading firearm.

Abstract: A muzzle-loading firearm having a breech loading receiver including a locking mechanism movable between an open position and a locked position; a barrel having a breech end engaging the receiver and a bore extending from the barrel's breech end; and a firing module receiving plug positioned within the barrel's breech, the plug including a chamber axially aligned with the barrel bore to receive an ejectable firing module having an igniter within a chamber.
