摘要： Firearms, with gas-operated reloading, having a gas block that includes a gas pressure selector movable between at least two positions. For smooth operation, the gas pressure selector in the gas block is rotatable into at least two positions about its primary axis and is also designed to be axially displaceable along the same primary axis between at least two positions. The gas block includes a stop pin that is arranged to cooperate with a control surface of the gas pressure selector with complementary form and function, and further includes a locking device having a spring-loaded locking pin that can yield normally to the primary axis to temporarily lock the gas pressure selector in a predetermined position.

摘要： 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.

摘要： Gas-operated firearms, in which the gas system guides gas selectively from the gas removal bore to a gas pipe, with a platelet, movable between at least two positions in the gas system. The platelet may be pivotable about a pivot axis pin. A stop pin, parallel to the pivot axis pin, may protrude into a stop bore of the platelet, thus delimiting the pivoting. The platelet may have at least two recessed catch positions, into which a catch, under the effect of a catch spring, optionally engages, provided that the gas through-bore associated with the catch comes to rest in alignment between the gas bores when the catch engages in one of the recesses.

摘要： 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.

摘要： A safety selector for a firearm, including a first lever including an integrally formed safety shaft and a first handle located outside the lower receiver for actuation, as well as a bearing portion, a selector portion and a connecting portion. To facilitate disassembly and interchangeability, the first lever is configured for spring-biased coupling to a securing element and has, on the connecting portion, a positioning protrusion projecting toward the opposite side of the weapon. In a longitudinal direction, the positioning protrusion has a shape-complementary bore for receiving a connecting assembly which includes a connecting element, a spring and a spring lock.

摘要： 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.
