20140317983 | RIMFIRE TYPE FIREARMS HAVING CENTERFIRE FIREARM COMPONENTS AND RELATED METHODS - Firearms include some components originally configured for use with centerfire cartridge ammunition, such as a lower portion, and other components configured for use with rimfire cartridges, such as an upper portion and magazine. The firearm is thus configured for firing rimfire cartridge ammunition, although some components of the firearm may be characterized as centerfire firearm components. Methods of fabricating firearms involve assembly of a rimfire upper portion with a centerfire lower portion. A magazine is provided that is configured to couple to the centerfire lower portion, and to feed rimfire cartridges from within the magazine into the rimfire upper portion. Methods of adapting a centerfire firearm for use with rimfire cartridges involve removal of a centerfire barrel and upper portion from a centerfire lower portion, and attachment of a second upper portion and a second barrel, each configured for use with rimfire cartridge ammunition, to the centerfire lower portion. | 10-30-2014 |
20150096213 | TOP LOADING SHOTGUN - A shell feeding system for a top loading shotgun in one embodiment includes a barrel, receiver, and a magazine. The magazine includes a cavity configured to receive a plurality of ammunition shells in stacked end-to-end relationship. The magazine is positioned above the barrel and extends forward from the receiver. Shell guide grooves are formed by internal surfaces in the receiver which engage and guide each shell in a feed pathway towards the lower part of the receiver for chambering. A portion of the guide grooves may be arcuately shaped to rotate and reposition the shell for loading by the bolt into the chamber. In one embodiment, the receiver and magazine may be formed as a unitary integral structure formed as either a single piece or in half sections coupled together. | 04-09-2015 |
20150300772 | DOUBLE-BARREL PUMP SHOTGUNS - An improved shotgun design that includes at least two barrels, a trigger assembly that allows for individual simultaneous firing of each barrel, a single magazine with parallel ammunition wells that each feed one barrel, and a single slide mechanism that actuates the loading/unloading mechanism and resets the firing mechanism for discharge of subsequent rounds. | 10-22-2015 |
20150323271 | AMBIDEXTROUS BOLT CATCH AND MAGAZINE RELEASE AND FIREARM - Firearms where the bolt catch, magazine, or both, can be released from either side using the same or a substantially similar motion using contact features that look, feel, or operate similarly on both sides, that are located within the firearm rather than externally, that can be used more easily or reliably, or a combination thereof. In some embodiments, a bolt catch engagement feature is similarly ambidextrous. In many embodiments, a user action on one side of the firearm is substantially similar to, but in the opposite direction from, a user action on the other side that performs the same function. In various embodiments, a left button, pad, or feature is directly opposite and in line with a right button, pad, or feature. Bolt catches can use two levers and magazine release mechanisms can use two parallel elongated members that are perpendicular to the barrel with a catch actuator located between. | 11-12-2015 |
20160040956 | LEVER-ACTION MODULAR TACTICAL RIFLE - A lever-action tactical rifle having an upper receiver assembly having a rifle barrel and a hand-guard. A lower receiver releasably and pivotally connected with the upper receiver and having a butt-stock and a magazine receptacle releasably containing a cartridge magazine. A bolt mechanism having a bolt carrier and a bolt member and firing pin being located for reciprocating movement within the upper receiver. A lever-action mechanism is mounted to the lower receiver and is connected with the bolt carrier by an actuating linkage. The bolt member has cam slots being engaged by cam pins of the bolt carrier to translate linear movement of the bolt carrier to rotation of the bolt for bolt locking and unlocking. | 02-11-2016 |
20160047610 | SHELL LOADING SYSTEM FOR FIREARM - A shell loading system for a firearm in one embodiment includes a barrel, receiver, reciprocating slide and bolt assembly, tubular magazine, carrier operable to receive and feed shells from the magazine into the action, a spring-biased carrier latch laterally moveable to engage the carrier, and a pawl pivotably mounted on the carrier. A carrier latch disconnect is also pivotably mounted to the carrier and operated by the pawl. The carrier latch disconnect and pawl are movable independently of each other in one embodiment. The carrier latch disconnect is operable to block the carrier latch from engaging the carrier in a first position. In a second position when activated by the pawl, the carrier latch disconnect releases the carrier latch to engage the carrier which is locked in a downward position to receive a shell from the magazine. | 02-18-2016 |

20090000171 | FIREARM RECEIVER WITH EXTENDED BRIDGE - A firearm receiver with an extended bridge is created to prevent the fully automatic fire of an assault rifle. The extended bridge receiver has a narrowed magazine well for a single stack removable magazine, safety catch with one or more grooves on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and barrel extension permanently attached to the muzzle. The receiver can be configured with a rivet on the bridge in a location that prevents backward turning of the safety catch, where the modified safety catch has two positions (i.e. safe and fire), rather than the three positions consistent with a fully automatic firearm. In a second version, the extended bridge lacks a release lever groove. In yet another version, an inseparable, double stack magazine box is used. | 01-01-2009 |
20100162604 | LIGHTWEIGHT, LOW COST SEMI-AUTOMATIC RIFLE - A lightweight and low cost semi-automatic rifle includes an upper receiver, a lower receiver, and a forend fabricated from injection-molded polymers. The rifle permits firing .22 LR or similar low-power ammunition from an AR-15 style frame, operates on the blowback principle, and provides a fully functional bolt catch and extractor/ejector/deflector. | 07-01-2010 |
20110056107 | FIREARM RECEIVER WITH AMBIDEXTROUS FUNCTIONALITY - Embodiments of the present invention provide firearm receiver with ambidextrous features. Some of these features include a bolt-locking mechanism on a firearm receiver that is configured to allow an operator to clear jams while maintaining hold of a firing grip. The bolt-locking mechanism may include a linking mechanism configured to manipulate a bolt-catch device in response to activation of a magazine release button on a firearm receiver. Other features include an ambidextrous magazine release mechanism on a firearm receiver that is configured to allow an operator to release an inserted magazine while maintaining hold of a firing grip with either hand. The magazine release mechanism may include a linking mechanism configured to manipulate a magazine catch device in response to activation of either a right-handed magazine release button or a left-handed magazine release lever that pivots on an external fulcrum on a firearm receiver. | 03-10-2011 |

20100154268 | SEMI-AUTOMATIC WEAPON FOR SEVERAL TUBES CARTRIDGES LOADING SYSTEM FOR LONG GUNS - New design for semi-automatic weapon for several tubes cartridges loading system for long guns, wherein an in-between connection steel part fixes the barrel to the receiver. The retention of the cartridges inside the parallel tubes is done by three metallic nails. The springs of the loading tubes push the cartridges into the cylinder inside the gun through three openings made into the front side of the receiver under the barrel. The rotation mechanism of the cylinder is a result of changing the movement of the bolt from horizontal into vertical. | 06-24-2010 |
