摘要： A feed ramp system (5) for feeding cartridges into the chamber of a firearm (10). The feed ramp system includes a feed ramp insert (60) having a body with at least one attachment tab (66) projecting therefrom. The feed ramp insert (60) is received within a mating recess (54) formed in the receiver (40) and is removably coupled to the receiver to enable replacement of the feed ramp insert. The feed ramp insert (60) includes a pair of proximal ramp surfaces (68) that align with distal ramp surfaces (38) formed at a breech end (22) of the firearm barrel (20), to define a pair of feed ramps (76) for directing cartridges into the chamber.

摘要： Automatic weapon comprising a barrel assembly (6) mounted movably in the housing (1), a barrel (7) and a receiver (8), a gas removing engine (17), a bolt support (24) with the bolt (22), a buffer mechanism (32), a feeding mechanism, a device (61) of feeding cartridges into the cartridge chamber, a firing pin mechanism (33) and a trigger mechanism (50); the firing hammer (36) of the firing pin mechanism (33) is made to travel along the axle of the weapon and is mounted with the possibility of interaction with the bolt support (24). the trigger mechanism (50) is made in the form of a firing trigger (52), a tripper (53) and a sear (43) kinematically connected with each other. The tripper (53) has cam surfaces designed to interact with the spring-mounted pawl (48) made on the sear (43) which can interact with the firing hammer (36) said tripper (53) is rotatably and slidingly mounted an on axle (54), which lies parallel to the longitudinal axis of the weapon, so that said tripper (53) can travel in parallel to the longitudinal axis of the weapon. The device of angular displacement (3) of the barrel assembly (6) relative to the housing (1) is made in the form of a guiding element (4) interacting with the support base (5). The invention reduces bullet dispersion when firing by bursts, increases effectiveness of automatic fire of the weapon.

摘要： A light-weight firearm and related fabrication method are described for a wear resistant feed ramp for chambering cartridges from an ammunition magazine. In one embodiment, the firearm includes a barrel and a frame defining a magazine well and cartridge feed ramp. A wear insert formed of a different material than the frame is implanted in the feed ramp adjacent to the barrel chamber. The wear insert is then machined in situ to shape forming an obliquely angled wear surface. After machining, both the frame and implanted wear insert undergo a surface hardening process together. The surface hardened wear insert has a greater surface hardness than the surface hardened frame and is better adapted to resist wear after repeated chambering of rounds. In one non-limiting example, the frame may be hard anodized aluminum and the wear insert hard anodized titanium.

摘要： Applicant has disclosed a Method and Apparatus for stripping and feeding cartridges to enhance stripping cartridges out of a detachable double-stacked magazine, inserted into a (well opening of a) receiver of a bolt-action rifle, and to enhance feeding the cartridges into the firing chamber. In the preferred “apparatus” embodiment, Applicant's device comprises two protrusions (“bumps”) integral with, and radially spaced around, a bottom of the breech bolt head. When the rifle's breech bolt is pushed through the receiver, towards the firing chamber, a flat front face of a protrusion engages the rim of the top cartridge, pushing the cartridge out of the magazine, over the feed ramp or lip, and towards a firing chamber of the rifle. The protrusions alternate as to which engages the next top cartridge(s), due to the staggered (zigzag) columns of the cartridges in a double-stacked magazine.

摘要： The invention relates to an arrangement of locking projections (21) at the locking head (19) of a locked self-loading hand gun. The locking head (19) can be mounted in two different ways, whereby the cartridge extractor (23) is arranged horizontally to the left or right. A locking projection (21) is omitted at the place of the cartridge extractor (23) so that an uneven number of locking projections (21) is provided. The locking projections (21) are arranged in such a way that they extend along both sides of the lips (27) of a given magazine when the lock (3) is released instead of being distributed over the circumference of the locking head (19) with the same angular distance.

摘要： The invention relates to a device and a method for loading a cartridge (3) into a battery (2) of a barrel (1) of an autoloading firearm. Said device comprises a bolt (8) which is able to slide in the longitudinal direction of the firearm and serves to move the cartridge (3) and to introduce said cartridge (3) into the battery (2). The invention provides for at least one centering element (5b) which is irremovably fixed to the barrel (1) and serves to center the bolt (8) in relation to said barrel (1).

摘要： The invention relates to a semi-automatic small arm with a breech (5) that can be displaced between a closed position and an open position along a path of motion of the breech, a magazine (9) that guides bullets by spring power transversely to the path of motion of the breech until they reach said trajectory and a catch (13) which allows the respective first bullet (11) of the magazine (9) to enter the path of motion of the breech only if the breech (5) is in the open position or close to the open position. The catch is preferably configured as a plate (13) that extends parallel to the path of motion of the breech and that is movable in its direction of extension. Said plate interposes itself between the respective first bullet (11) and the path of motion of the breech and retains said bullet (11) until the breech (5) reaches or has almost reached its open position.
