A weapon which has a modular design. The weapon is subdivided into weapon-specific modular assemblies which are designed as carrier units of the components. The modular assemblies include a weapon housing into which a breech system of the weapon and a striking mechanism is provided, a weapon cradle that connects with the weapon housing, and a weapon barrel module. The modular assemblies are connected to each other by rails and guides, by binders and holders, by pins, or by bolts and quick release fasteners.

A bolt carrier for a firearm, including lugs on the first end to engage corresponding lugs of a barrel receiver/extension. The bolt carrier includes a cam slot within which a cam pin from a bolt is constrained to travel along a cam slot path during rotational and translational movement of the bolt. The cam slot defines (1) a first cam slot means for constraining motion of the cam pin and the bolt during engagement or disengagement of the lugs of the bolt and the corresponding lugs of the barrel receiver or extension; (2) a second cam slot means for imparting rotational movement to the cam pin and bolt during linear movement of the bolt carrier; and (3) a third cam slot means for constraining motion of the cam pin at an end of a rearward travel of the bolt and bolt carrier during an ejection cycle. The combination of the first, second, and third cam slot means yields an extension of the unlocking by over 10% and a delay of the actual unlock of the bolt by over 5% relative to TDP.

A captive recoil spring assembly includes a guide rod surrounded by a coil spring. The spring is captured between a base at one end of the guide rod, and a body at its opposite end. The body is shaped to engage the spring at one or more sectors, leaving one or more remaining sectors free to engage the slide. Use of such a body permits a round wire spring to be used without the need for close dimensional tolerances on the engaging parts.

Invention refers to a breech mechanism of a pistol with a barrel which is tilting during the recoil. Barrel (1) ledge (3) at the bottom has long slots (7), placed along its lateral surfaces, which intrude in corresponding guides (8), performed in frame (5), and the front side of the barrel (1) is placed in the slide (4) guiding hole 6.Besides that, barrel (1) ledge (3) has opened transverse slot (9) with radial edges, situated with bottom-upward tilt and close lateral hole (13). In the long slot (9) the roller (10) is placed, which is pressed up by the spring (11), situated at the closed hole (13), closed by the socket (12). On the inner sidewalls of the frame (5) bevels (14) are performed, on which the roller (10) ends are sliding and on the inner sidewalls of the slide (4) cuts (15) are performed, wherein the roller (10) ends intrude, when the slide (4) is on the forward position.

This disclosure relates to self-contained cartridges and launcher systems for discharging or launching payloads to downrange targets, and methods of attenuating or offsetting recoil when activating such cartridges. Examples of payloads that can be deployed with the disclosed launcher apparatus include chemical, biological, pyrotechnic, marker, tracer, signaling, non-lethal, explosive, smoke, and similar payloads.
摘要:
A bolt assembly with improved rotating locking head, comprising a rotating locking head associated with a bolt body and movable with respect to the bolt body with a combined rotary and translational motion; the rotating locking head having at least two working positions: a closed position, wherein the rotating head closes the breech of the firearm, and an open position, wherein the rotating head is at a distance from the breech; the bolt assembly has an auxiliary pusher that biases the rotating head from the open position to the closed position.

Embodiments of the present disclosure provide modifications to the AR platform operating system such that the platform now is competent to fire large caliber cartridges, including belted cartridges, providing longer range and greater barrier penetration without substantially altering the characteristic features and component inter-relationships of this platform.
摘要:
A firearm has a frame with an interchangeable barrel that is mounted to the frame through a tool-less knockdown pin. The barrel has ports in a smooth-bore section and no ports in a rifled-bore section, and the ports are progressively spaced, with the ports closest to the rifled-bore section having a greater distance between the ports than the ports closest to the muzzle. Preferably, the firearm is a multi-chamber design such as a revolver with a firing cylinder or a multi-barrel breech-loader that holds multiple rounds of ammunition together with a storage-firing clip while stored in an ammunition compartment and also when loaded into the firing chambers and discharged by the firearm. The frame preferably has a trigger mechanism with a sear assembly that includes a block assembly with a wedge block that translates on a guide rod and a disconnect block that is supported by a disconnect rest.

A rifle having a receiver formed of upper and lower receiver portions attached to one another has one or more elastic bodies positioned between facing surfaces of the upper and lower receiver portions. The elastic bodies reduce play or lost motion between the upper and lower receiver portions for improved accuracy.
摘要:
A side lock action firearm has a frame with an attached side lock action. The frame includes a rearwardly protruding portion including a mating feature. A stock including a mating element is removably connected to the frame when the mating element is engaged with the mating feature. The mating feature may be a threaded boss. The mating element may be a draw bolt. A forward portion of the stock may be shaped to closely receive the rearwardly protruding portion of the frame. The stock may include a central bore, and the draw bolt may be received by the central bore in the stock.
