Abstract: Firearms including a secured firing pin retaining pin, the firearms having a barrel, a sliding block, a bolt head, a firing pin with a flange-like collar, a firing pin retaining pin with a safety device, and a weapon median plane. For facilitating handling, it is provided that the firing pin retaining pin is slidably mounted normally to the weapon median plane in a retaining bore, that it is designed as one piece and to be rotationally symmetrical with a head and a pin end and has two annular grooves. A locking pin mounted in a spring-loaded manner in the sliding block is designed such that, depending on the position of the firing pin retaining pin in the retaining bore, it can optionally engage in one of the annular grooves, which correspond to a holding position and a release position for the firing pin, respectively.

Abstract: A handguard for mounting on a firearm with a housing axis, including: a housing with a slit and with a clamping device including a lever with a center element which lies in a normal plane to the housing axis in a through-opening. It has a recess in its central region, a thread at one end, a lever arm at the other end, and a nut with an internal thread. According to the invention, the center element has a conical nut section. In the assembled state, a nut is screwed onto the thread and thus the center element is arranged in an annular groove of the travelling nut so as to make contact with the center element.

Abstract: 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.

Abstract: A barrel for a firearm having a bore axis, a cartridge chamber, and an integrally formed locking sleeve with a locking space, with locking lugs, the locking sleeve has recesses for bolt head lugs of a bolt head to be inserted. The barrel has, in the direction towards the cartridge chamber, at least two centering ramps in the transition area between the recess for the lugs and the locking space in an oblique manner with respect to the bore axis. Further the recesses forming the bayonet-type groove, viewed in the direction of the bore axis, each have a profile which comprises an elliptical segment. The disclosure additionally provides a production process for such a barrel.

Abstract: A trigger unit for a firearm, including a hammer rotatable about a hammer axis and prestressable by a hammer spring, a trigger lever rotatable about a trigger axis, the trigger lever has a trigger and a trigger rear, which receives at least one interrupter. A sear is rotatably mounted about a sear axis and prestressable by a sear spring. The sear axis and the trigger axis coincide, and the sear has a bearing recess for receiving and limited rotation about a disconnector axis of a disconnector pivot formed on the underside of the disconnector, the bearing recess being formed surrounding the disconnector pivot at least partially in the direction of rotation about the disconnector axis.

Abstract: 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.
