Firearms including a bolt catch device, having a receiver comprising a duct, wherein the bolt catch device comprises a foot, a slider, and a spring, and the foot, on the leg thereof and on the magazine well side, has a groove for receiving the spring and, on the side facing the trigger device, has a socket; wherein the slider has, on the lower portion thereof, bearing bolts for being inserted into and pivoted in the socket, wherein the slider has, at the upper end thereof, a protrusion which protrudes in the direction of the magazine well beyond the contour of the duct, and wherein the receiver has an abutment that protrudes into the groove in order to prestress the spring of the bolt catch into the rest position.

Rifles comprising a bolt catch device

A bolt for a firearm having an extractor for cartridge cases, comprising a cylindrical body having a locking portion with a breech face, an undercut, groove-shaped, rearwardly-running recess for an extractor with an extractor claw and a leaf spring, as well as an inwardly-projecting bearing protrusion and a second lever arm with a rearwardly-projecting spring bearing portion. The bearing protrusion is designed to be hook-shaped so as to abut against the extractor axis in the installed state with a bearing opening open rearwardly, and, on the body, the groove-shaped recess for receiving the leaf spring is laterally open at least partially on one side tangentially to the circumferential direction, via an insertion portion, and is designed to merge laterally and/or rearwardly into the undercut, and the body has a cavity for receiving the bearing protrusion relative to an imaginary plane of the recess in the region of the extractor axis.

Bolt for a firearm

A firearm with a clamping device for attaching a barrel with a barrel extension, where the barrel extension on the one hand, and a seat on the other hand, possibly directly the upper receiver, are connected to one another by means of a clamp and the fixing of the barrel extension on the upper receiver by means of a tension lever that is rotatable about a common axis of rotation running normal to the weapon center plane between two end positions, the ready-to-fire position and the dismantling position, with at least one clamping section and a grip and a cam formed on the tension lever.

Firearm with barrel clamp

A firearm including a gas drive, having an annular piston which is displaceably arranged on the barrel to form an expansion chamber between two end positions. At least one gas port penetrates the wall of the barrel in the region of the expansion chamber and a selector is provided. In order to provide a simple and easily adjustable mechanism, the expansion chamber is delimited by a ring surface and an inner cylinder surface of the piston, an end surface of the selector and the barrel. The selector is rotatably arranged on the barrel with at least two predefined rest positions. In each rest position, the gas flow from the expansion chamber is delimitable by at least one selector opening formed on the selector.

Firearm with gas drive

Firearms with cartridge-case ejection, including a barrel with a movable bolt carrier with a bolt, with a breech face, with a movable ejector and with a firearm-fixed functional edge which pushes the ejector into its ejection position when the bolt carrier moves back after a shot has been fired. In order to create an ejection that is always evenly performed, an ejector lever is arranged on the bolt carrier so that it can be rotated about a pivot axis running normal to the firearm's central plane, which abuts against the functional edge when the bolt carrier moves backwards and thereby twisted so that it abuts an impact surface of the ejector and forces it to the eject position.

Weapon with cartridge-case ejection

Rifles having a weapon median plane, with a barrel with a barrel bore axis, a gas drive, a sliding block, a closing spring unit, and a charging handle assembly arranged in front of the sliding block, where the charging handle has two operating handles pivotally mounted about pivot pins on a slider body, said operating handles being pushed about the pivot pins into their rest position by at least one handle spring. For facilitating the use and especially the forward shift of the charging handle, the slider body is mounted on a carriage which is arranged axially in front of the sliding block and movable in the axial direction.

Carbine with charging handle assembly

Breechblocks for firearms, the breechblocks including a barrel axis and a barrel extension, including a bolt with cam pin and cam pin axis, and a bolt carrier which has at least one end face and an assembly groove and a substantially S-shaped cam slot with a locked position and an unlocked position, wherein the assembly groove at the locked position of the cam slot is subsequently formed substantially from behind in the forward barrel direction and is essentially U-shaped.

Breechblock for a firearm

Firearms, particularly rifles, including an upper housing having a barrel, where the barrel and the upper housing are interconnected by means of a guide. In order to improve the connection, the guide includes corresponding prismatic guide surfaces that extend in parallel with the barrel shaft when the firearm is mounted and ready to fire, and the barrel is secured to the upper housing by a tensioning element that can rotate in the upper housing about an axis of rotation that extends normally with respect to the firearm center plane, and the tensioning element includes a tensioning portion and an actuating portion.

Firearm with improved barrel connection

A rifle with a barrel firmly mounted in a framework, the barrel including a locking sleeve, a lock, a sliding block, and a gas-powered actuator. Advantageously quiet operation of the gas-powered actuator is accomplished when the actuator has an annular piston, which is movable on a plunger support, forming an expansion chamber, where the actuator acts on the sliding block via push rods and is pushed forward by reset springs, and the rifle further includes a gas borehole penetrating the walls of the barrel and the plunger support, and further where the plunger support includes an outlet channel in its front, upper range, which is fluidly separate from the expansion chamber when the annular piston is at rest, and is fluidly connected with the expansion chamber after a backward displacement of the annular piston.

Handle part for a handgun

A rifle has a barrel which is mounted detachably in the housing in that pairs of clamping rings (,) are provided between the rear part of the barrel (,) and the inner cylindrical surface (,) of the housing (,), which clamping rings (,) have mutually facing conical surfaces and are pressed axially by a clamping nut (,) against a collar (,) on the barrel (,). Such a barrel mounting can also be used for a housing made of light alloy, with simple production and with production-dependent tolerances and alignment errors being eliminated.

Gun with detachable barrel mounting

A hand-held firearm, comprising a casing which accommodates breech parts, a stock which is attached to the casing, and a barrel which is detachably connected to the casing, and having a mounting for a telescopic sight. In order to avoid the disadvantages of the conventional telescopic sight fitting and to allow the entire weapon to have a neat and practical shape, the casing forms a casing extension at the front beyond the connection to the barrel and a longitudinal rail is integrally formed at the top on the casing and on the casing extension as a mounting for the telescopic sight. The casing parts are made of light metal alloy.

Hand-held firearm with a light casing

A rifle has a fore-end to which a bipod is fitted which comprises a support part and retractable legs, the support part and the legs being connected by means of pins, which are thickened at their outer end and have a cut-off sector, and depressions with an interrupted circumferential lip. In order to provide a simple, cheap and elegant bipod, the support part is mounted on the fore-end such that it can rotate about a shaft located in the firing direction, the pins are part of the leg and the associated depressions are provided in the support part, and the support part and leg have a circular groove and a circular bead which fits into the groove and projects in the direction of the axis of symmetry of the pin, the axis of the groove and bead being the same as the axis of symmetry of the pin, and their diameter being larger than the maximum diameter of the pin.
