The receiver assembly includes a receiver having a magazine well, a locking device having a locking lever for actuating the locking device, a control block accommodated in the receiver, a trigger pivotable in the receiver and about a trigger axis, a sear bar coupled to the trigger, a locking bar having a guide lug, and a lowering component accommodated in the control block, which has a bar guide slot formed therein. The sear bar extends to the control block and includes a guide bracket. The locking bar interacts with the locking device. The lowering component is displaceable for removing the slide assembly from the receiver assembly. The lowering component includes a control window and a guide link. The guide bracket is guided in the control window. The guide lug protrudes into the guide link and through a bar guide slot of the control block.

Abstract: A locking device for installation in a receiver assembly of a firearm. Unlocking the locking device allows removal of the slide assembly from the receiver assembly. The locking device includes a locking slider having a retaining lug, first and second guide members each formed on the locking slider, and a locking lever. The retaining lug may interact with a barrel to limit a movement of the slide assembly relative to the receiver assembly. The first and second guide members are received in first and second receiving slots, respectively, of a grip/receiver. The locking lever is pivotable about a pivoting axis and is couplable to the locking slider in such a way that the locking lever serves to actuate the locking slider. A transfer of the locking slider from a retaining position to a release position is effected by rotation of the locking lever.

Abstract: A trigger unit for a firearm, including a rotatable trigger lever in which the trigger lever has a trigger bar which lies below the trigger axis and is moved when the trigger bar is actuated against a barrel direction, and a fire-control/safety selector for selecting at least one “safe” and one “fire” position, where a locking lever rotatably mounted about a locking lever axis is arranged in the trigger unit and is biased in a circumferential direction by a locking lever spring, and that the locking lever axis, when viewed in the barrel direction, is arranged behind the trigger axis, and the locking lever is designed to releasable fix the fire-control/safety selector in a selectable position.

Abstract: 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.

Abstract: Modular systems including a trigger unit for a firearm, wherein the trigger unit is designed as a drop-in trigger unit to complement a trigger pocket of the lower receiver of the firearm, and that the trigger pocket is received by the trigger housing, preferably completely.

Abstract: 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.

Abstract: A bolt catch lever for a firearm, including receivers and associated elements for receiving the bolt catch lever. In particular, a bolt catch lever comprising an upper lever arm, a lower lever arm, and a center element including a catch which is designed so as to be pivotable about a pivot axis in a lower receiver, where the center element has a recess for optionally receiving a connection section of a second bolt catch lever.

Abstract: 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.

Abstract: 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.

Abstract: Mounting device for accessories of a firearm, and accessories with such integrated mounting devices, the firearm having guide elements with a recess, where the mounting device has at least one bearing knob and at least one locking spindle configured to cooperate with the bearing knob and the at least one recess. The at least one locking spindle has a selector knob with a resting protrusion, a connection piece and a center part on which at least one locking protrusion is formed. The locking spindle is rotatably and/or longitudinally displaceable in the device housing and is arranged to interact with the bearing knob and the spring.

Abstract: 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.

Abstract: Firearms including a slide, an ejector and an extractor assembly, which extractor assembly includes at least one stirrup-shaped extractor, a plunger and a biasing element.
