| 20110005116 | MUZZLE LOADING RIFLE WITH BREECH PLUG HAVING GAS SEAL FACILITY - A muzzle loading firearm has a barrel with a bore on a bore axis, and the barrel has a muzzle end and a breech end. A frame is connected to the barrel, and has a breech face. The frame moves between an open position in which the breech face is away from the breech end of the barrel, and a closed position in which the breech face abuts the breech end of the barrel. A breech plug is removably attached to the barrel. The breech plug including a seal element closely received by the bore. The seal element may be a set of piston rings that are received in a circumferential groove about a forward end of the plug, or may be a cup at the forward end, with a forward rim that flares under pressure to provide a gas seal. | 01-13-2011 |
| 20100281732 | MUZZLE LOADING FIREARM WITH BREAK-OPEN ACTION - A muzzle loading firearm with a break-open action includes a rear stock assembly and a barrel assembly. The barrel assembly includes an elongate barrel, having a bore with muzzle and breech ends, and a breech plug removably connected the breech end of the barrel, which encloses a chamber at the rear of the bore. The barrel assembly is pivotally attached to the rear stock assembly, and is movable with respect to the stock assembly between an open position in which the breech end is accessible for service, and a closed position in which the breech end is inaccessible and secured for discharge. A lever arm, optionally configured to serve as the firearm trigger guard, is user actuated for moving the action between the open and closed positions. The breech plug is configured for rapid removal from the barrel by hand when the action is open. | 11-11-2010 |
| 20100162606 | FIREARM MAGAZINE AND ADAPTER THEREFOR - A firearm magazine includes a housing defining a cavity. A resilient member is disposed in the cavity. A cartridge support member is movably supported on the resilient member and configured for moving downwardly into the cavity against increasing tension of the resilient member when the magazine is being loaded. The resilient member when under tension urges the cartridge support member and cartridges thereon to move upwardly during a feeding operation. An adapter converts a firearm magazine from multiple cartridge capacity to single cartridge capacity, and is configured to be removably coupled to the upper housing to cover the cartridge support member of the housing. The adapter includes an additional cartridge support member. The housing and the adapter cooperate to prevent the additional cartridge support member of the adapter from being moved downwardly into the cavity. | 07-01-2010 |
| 20100162605 | BOLT ACTION FIREARM - A bolt action firearm includes a bolt assembly with a bolt body having an outer surface defining a longitudinal guide channel extending along a length of the bolt body from a rearward end to a forward end. A receiver defines a central longitudinally extending bore for accommodating the bolt body. A bolt guide is configured to be coupled to the receiver. The bolt guide includes a projection configured for traveling in the guide channel when moving the bolt body in the receiver so as to ensure that the bolt body is at a predetermined correct angular orientation within the receiver. | 07-01-2010 |
| 20100024272 | MUZZLE LOADING RIFLE WITH REMOVABLE BREECH PLUG - A muzzle loading firearm has a barrel with a bore on a bore axis, and has a muzzle end and a breech end. A frame is connected to the barrel, and has a breech face. The frame moves between an open position in which the breech face is away from the breech end of the barrel, and a closed position in which the breech face abuts the breech end of the barrel. A breech plug is removably attached to the barrel, and is connected to the barrel by way of interrupted, or multistart threads, or locking lugs. The breech plug may have a rear face that abuts the breech face when the frame is closed, so that a primer contained in a primer pocket in the rear of the breech plug is fully supported on all sides. | 02-04-2010 |
