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 device for forming a secondary mount of a handguard on a firearm, wherein it is possible to bring the upper receiver of the firearm into a partially dismantled state from the lower receiver by tilting about a front takedown pin and/or into a dismantled state by removing (a pin), there being in the mounted state an elastic clamping connection between the handguard and the upper receiver and/or a barrel mount connected to the upper receiver, which barrel mount comprises at least one clamping element and at least one abutment, and the clamping element is designed such that when the handguard is connected or removed, an elastic deformation of at least one part of the clamping element takes place, and such that, in the mounted state, there is resilient prestressed contact with the abutment and/or at least partial accommodation in the abutment.

Secondary handguard mount

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

Firearms having an upper receiver part and a lower receiver part that are detachably connected to each other by a connecting mechanism so that the two receiver parts are pivotable relative to each other between a closed and an open position. The connecting mechanism includes at least one pivot pin, running normal to the median plane, and a pivot pin hole passing through the upper and/or the lower normal to the median plane, a connector element with at least one hole and a slotted hole and a protrusion formed on the upper or lower, running in the direction of the barrel axis, and a recess which is complementary thereto in shape and function.

Connection for the upper receiver part and the lower receiver part of a firearm

A trigger unit for a firearm, including a trigger bar that lies below the trigger axis. A trigger lever has a rear which accommodates at least one disconnector. A sear, rotatable about a sear axis can be biased by means of a sear spring. The hammer axis, the trigger axis and the sear axis are arranged parallel to one another and parallel to a transverse direction. The trigger lever has a recess and the sear is at least partially arranged within. The sear axis and the trigger axis coincide. The sear limits rotation of a disconnector joint formed on the underside of the disconnector; the bearing encloses the disconnector joint at least partially.

Trigger for a firearm and a firearm equipped therewith

A barrel unit for a firearm, including a barrel with a barrel axis, muzzle and a barrel end opposite the muzzle, on which at least two barrel lugs are formed, and a barrel extension with a barrel receptacle and a first end and a second end, wherein inwardly extending locking lugs are formed on the first end, to work together with a bolt, and inwardly extending barrel locking lugs are formed closer to the second end than the locking lugs. A barrel cam on the outer surface cooperates with a cam lug arranged on the barrel extension to fix the barrel in a predefined end position.

Barrel unit 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.
