Gun stock // 2520175

FIELD: weapons and ammunition.

SUBSTANCE: stock of small arms like "bullpup" automatic weapon with a carriage is made based on a metal enveloping guide for a moving firing unit with possibility of its preliminary roll-out to perform a "fixed string" of three-four shots. Bends of the enveloping guide of the stock, which face each other, are equipped with upper longitudinal ribs with possibility of enveloping the bends. Elements facing downwards and arranged on lateral sides of the metal base of the firing unit prevent movement to sides of bends of the enveloping guide of the gun stock. On lower surface of the enveloping guide stock from the nose piece of the back plate and to the muzzle part, which envelopes from below the guide stock of a cross piece, there arranged are two strengthening longitudinal stiffeners forming side walls of a collar of a lower longitudinal window in the middle part of the stock for lower sleeve ejection. In the muzzle part of the stock there formed are side connection elements for arrangement under the fore-end of "bayonet-knife" attachment elements or an under-barrel-mounted grenade dispenser, which are attached onto the guide gun stock.

EFFECT: improving stiffness of a gun stock and reducing deformation loads at shooting.

SUBSTANCE: weapon comprises a vertical thrust rib, which supports a recoil spring of a weapon reloading handle at the back. In a breech part of a guide for device assembly there is a breech side narrowing that limits backward movement of the breech support element of the reloading handle recoil spring, and the breech slot of the reloading guide handle. The breech slot is made as capable of letting a breech vertical rib of a movable firing weapon unit through the slot inside the breech side narrowing. As a bolt support recoils, the breech vertical rib of the barrel receiver is installed behind the connection of the breech end of the side gas piston and the muzzle side surface of the weapon bolt support.

EFFECT: improved technical characteristics of a device.

Gun stock // 2450234

FIELD: weapons and ammunition.

SUBSTANCE: gun comprises a spring return mechanism for a movable firing unit and a guide stock as a mount for the latter. On a guide stock there are two gun handles for fire control installed in front of a lower box-shaped magazine, which is stable in process of firing, and a lengthy neck of a lower window serving for ejection of cartridge cases. A stock for a movable firing unit equipped with an intermediate magazine with an internal lever cartridge feeder comprises a metal component based on a profiled carrier lengthy element and polymer components. Polymer components are made in the form of an upper longitudinal cover of a weapon that carries parallel recoil buffer of the firing unit and a return mechanism of a bolt support with a reloading handle, which is fixed in process of firing, under a longitudinal safety bracket. A protective neck for the lower longitudinal window and its lower cross links are connected with lower ends of weapon handles having polymer pads.

EFFECT: optimal ratio of strength and weight indices.

Small arms // 2438089

FIELD: weapons and ammunition.

SUBSTANCE: small arms have barrel receiver with barrel, bolt carrier assembly with bolt, gun stock with pistol grip, and firing mechanism made in single housing. Firing mechanism has safety lock made in the form of two-arm lever one of the arms of which is arranged in barrel receiver on the movement way of bolt carrier assembly with bolt. Barrel receiver and bolt carrier assembly are "П"-shaped. Side walls of barrel receiver have inward bends. Firing mechanism is fixed in the gun stock. On lateral side of safety lock arm, which faces the lateral side of barrel receiver, there is the stop tightly adjacent to the bend of barrel receiver in "Fire" position of safety lock. In longitudinal direction the stop of safety lock is arranged in rear part of the bend of barrel receiver. It is made symmetrically relative to vertical axis passing through rotation axes of the safety lock.

EFFECT: increasing arms safe operation.

Gun stock // 2435126

FIELD: weapons and ammunition.

SUBSTANCE: stock of automatic small arms with bullpup layout of a monitor gun class comprises a sliding joint with a male movable shooting device. The stock is equipped with a lower longitudinal window for lower ejection of cartridges. The window neck is placed between the right and left gun handles, the lower part of which by means of links is connected to the lower part of the neck. The base of the left handle of the gun is connected to the lower wall relative to the horizontal plane of the barrel in the longitudinal side pocket, which serves for passage of the side intermediate magazine of a gun shooting unit. The guide stock is equipped with a set for a hinged automatic fixator of the back position of a shooting unit, a trigger bracket and fixation elements of its upper longitudinal cover. The stock is made of polymer material. There is a cut facing the vertical plane of the gun on the gun handles. The cut serves to locate gunner's fingers in it. The vertical breech surface of every handle has larger width relative to the horizontal section of these handles compared to their muzzle part. The upper part of each handle has reduced thickness and increased longitudinal size. The vertical breech part of each handle with its upper part is located below the thumb of the gunner's hand holding this handle. The base of the right handle is arranged under the longitudinal tubular guide of the safety device.

EFFECT: reduced dimensions of a gun.
