Abstract: An integral sound suppressor for a gun barrel, with the integral sound suppressor including a tubular housing designed for nearly completely or completely encasing the gun barrel along its longitudinal direction with an internal thread disposed inside the housing for mounting the integral sound suppressor on an external thread disposed on the muzzle of the gun barrel. Disposed inside the housing is a deflector system for deflecting the gas generated by firearm discharge, and disposed on the housing is a guide surface which is spaced at a distance from the internal thread along the longitudinal direction of the housing for guiding the integral sound suppressor in the region of the front end of the gun barrel.

Abstract: A butt plate for a gun stock includes a holding part and a damping part which is attached to the holding part. An easy method of mounting and dismounting the butt plate can be implemented in that disposed on a front surface of the holding part, which front surface is facing the gun stock, are two forwardly projecting and spaced-apart arch-like retention members for snap-lock retention on two oppositely lying side walls of the gun stock.

Abstract: A gun lock of a firearm having two hammers movably disposed on a lock support, a trigger bar for each hammer for holding or releasing the hammers, a trigger, and a disconnector for the trigger, by which disconnector the trigger bars can be moved by the trigger from a holding position into a release position. The disconnector can be moved by an inertial mass between a triggering position, in which the trigger is connected to one of the two trigger bars, and a disconnect position, in which the connection between the trigger and the trigger bars is interrupted. The inertial mass is a pendulum mass swiveling about a transverse axis between a starting position and a safe position, by which the disconnector, upon the release of a first hammer, can be swiveled in a direction opposite to the direction of the pendulum mass into the disconnect position.

Abstract: A self-loading shotgun includes a lock movable inside a lock housing between an open position and a closed position, a barrel, a magazine disposed below the barrel, a lock catch for holding the lock in the open position, and a feeder system for lifting a cartridge delivered from the magazine to the height of the barrel. The feeder system includes a feeder that swivels about a transverse axis and a magazine hatch that interacts with the lock catch. To allow the self-loading shotgun to be fully loaded even when the lock is open, the swivel movement of the feeder generated by the lock is controlled by a control element separate from the lock catch.

Abstract: A hinged-breech weapon includes a receiver, a barrel part arranged to be tiltable around a rotational axis on the receiver, a front shaft removably fastened on the barrel part, and a bearing piece arranged on the rear end of the front shaft, when viewed in the firing direction of the hinged-breech weapon. The bearing piece includes rear bearing surfaces for pivotable mounting on the front mating surfaces of the receiver and a positioning device for adjustment of the position of the bearing piece relative to barrel part. The positioning device includes a clamping element movable in the bearing piece in the longitudinal direction of front shaft and adjustable by a control element for mounting on a stop arranged on the barrel part.

Abstract: A firearm with a housing, a barrel fastened to the housing, a bolt for closure of a chamber provided in barrel, and a hammer mechanism to operate a firing pin arranged in the bolt. The hammer mechanism contains a hammer strut arranged between the firing pin and a cocking piece, offset parallel to the firing pin.

Abstract: A slide for a rifle with a slide operating mechanism, which is movable in the longitudinal direction of the rifle, and a slide element, which can be moved by the slide operating mechanism between a locked position and an unlocked position. The slide operating mechanism is connected to the slide element via a control element, which is movable transversely to the slide element and is designed as a connector that cooperates with the slide element for its displacement between the upper, locked position and the lower, unlocked position.

Abstract: An adapter piece for mounting weapon accessory parts on a handheld firearm having a main body which includes mounting elements for detachably attaching the weapon accessory parts. To ensure flexible and accurate mounting of the weapon accessory parts, a fastening element for detachably attaching the main body to a front stock of the handheld firearm is disposed on the main body.

Abstract: A gun lock of a firearm having two hammers movably disposed on a lock support, a trigger bar for each hammer for holding or releasing the hammers, a trigger, and a disconnector for the trigger, by which disconnector the trigger bars can be moved by the trigger from a holding position into a release position. The disconnector can be moved by an inertial mass between a triggering position, in which the trigger is connected to one of the two trigger bars, and a disconnect position, in which the connection between the trigger and the trigger bars is interrupted. The inertial mass is a pendulum mass swiveling about a transverse axis between a starting position and a safe position, by which the disconnector, upon the release of a first hammer, can be swiveled in a direction opposite to the direction of the pendulum mass into the disconnect position.

Abstract: A removable magazine for a rifle with a support and a magazine insert disposed on the support, the magazine insert having, in the direction of fire, a back side and a front side with an opening for bullets of cartridges insertable into the magazine insert. The magazine insert is mounted on the support so as to be able to pivot around a transverse axis by a pivot bearing disposed on the back side thereof.

Abstract: A gas-operated firearm with a lock housing, a guide rod projecting forward from the lock housing, as seen in the shooting direction, for a lock activation device, which is located so it can be displaced on the guide rod and which interacts with a lock for its movement between a locking position and an unlocking position, and a barrel with a gas withdrawal block fastened on the lock housing, which contains at least one gas withdrawal borehole that opens into the barrel, and a pressure piston that is guided so that it can be displaced in the gas withdrawal block for the displacement of the lock activation device against the force of a lock spring. A simplified installation and dismantling of the barrel can thus be made possible in that the barrel contains a rear part, which can be placed on the lock housing and can be firmly connected with it, and a front part, which freely projects from the lock housing, without a firm connection with the guide rod.

Abstract: A mounting device for the detachable attachment of an aiming device on a handgun with a holding device which includes the clamping jaws for the detachable attachment of the holding device to the handgun and at least one recoil cleat for the positive locking engagement on the handgun. In order to enable a stable and accurately reproducible attachment of an aiming device, the recoil cleat includes two mutually facing and mutually separate engagement elements for the engagement in two mutually separate recesses on the handgun.

Abstract: A rifle stock with a support part which is attached in the rifle stock, and which includes, on its top side, a support area for the support of a receiver and/or of a barrel, and on its bottom side, a profiling for positive-fitting holding of the support part in the rifle stock. In order to make possible a bedding of the receiver and/or barrel that is not influenced by changes of the rifle stock, the support part is connected by an adhesive connection undetachably to the rifle stock.
