Abstract

A charging slide for carrying a bolt and latching a firearm in a folded position. The charging slide comprises a body, a projection, and a grip. The projection extends away from a first surface of the body along a first axis. The projection is configured to engage the bolt. The grip extends away from a first side of the body along a second axis oriented transversely to the first axis. The grip comprises a surface configured to engage an edge of a slot in a handguard of the firearm when the firearm is in the folded position. A receiver assembly and foldable firearm comprising the charging slide are also included.

IPC Classes  ?

• F41A 11/04 - Articulated or collapsible guns, i.e. with hinged or telescopic parts for transport or storage
• F41C 7/04 - Shoulder-fired smallarms, e.g. rifles, carbines or shotguns with reciprocating handgrip under the buttstock for loading or cocking

Abstract

A bolt catch is movably mounted on a firearm. A first surface of the bolt catch is configured to engage a bolt to retain the bolt in a first position. The bolt catch has a second surface that is configured to engage a follower of a magazine when the magazine is empty to position the bolt catch in a catching configuration in which the first surface is within a path of travel of the bolt. The bolt catch includes an elongate slot that extends transversely through the bolt catch. A pin extends through the slot of the bolt catch. The bolt catch is configured to pivot about the pin and slide relative to the pin. A spring biases the bolt catch rearwardly. Upon engagement between the bolt and the first surface of the bolt catch, the bolt catch is configured to slide relative to the pin to compress the spring.

IPC Classes  ?

• F41A 3/12 - Bolt action, i.e. the main breech opening movement being parallel to the barrel axis
• F41A 17/40 - Last-round safeties

Abstract

A recoil buffer assembly for cushioning the impact of recoiling components of a firearm. The recoil buffer assembly comprises a first spring, a second spring, and a buffer. The first spring extends along a first axis. The second spring extends along the first axis. The buffer is positioned between a first end of the second spring and a second end of the first spring. The first spring is configured to act between the buffer and a bolt within the firearm. The second spring is configured to act between an end of the firearm and the buffer. A receiver assembly and firearm comprising the recoil buffer assembly are also included.

IPC Classes  ?

• F41A 3/84 - Coil spring buffers mounted within the gun stock
• F41C 23/06 - Stocks specially adapted for recoil reduction

Abstract

A revolver has a detent mechanism providing positive mechanical engagement between the cylinder yoke and the frame. A housing mounted on the frame has a spring biased plunger that transversely engages a pin. The pin projects from the housing and engages a recess on the yoke when the revolver cylinder is closed. The pin is biased into engagement with the recess by the plunger to maintain the revolver closed and the chambers of the cylinder in precise alignment with the barrel during firing. Manual force applied to the cylinder can overcome the biasing force and permit the revolver to be opened and closed.
