摘要： Example methods, systems, and apparatus are described herein. An example gas block is described for an automatic firearm, which has a gas cylinder that can be connected in a fluid-tight manner to a hole in the gun barrel via a gas channel, characterized by a control element that can be switched between at least two positions and is designed to open the gas channel in the first position, in which the fluid-tight connection is obtained, and to close the gas channel in the second position, in which the fluid-tight connection is interrupted. The disclosure also relates to a control element, a gun barrel equipped with the gas block, and an automatic firearm equipped with the gas block.

摘要： The invention relates to a chambering device (1) for chambering rounds in an automatic firearm, which has a breechblock (119, 172) that can move longitudinally in a receiver (3), comprising: a loading lever (13, 13′), comprising a loading lever handle (15) coupled to a loading lever retainer (17), and a loading lever housing (59, 59′), which can move longitudinally in the receiver (3). The chambering device is characterized in that the loading lever handle (15) can be pivoted from a standby position to an actuation position and back in the loading lever retainer (17), and the loading lever retainer (17) can be mounted in or on the left or right side the loading lever housing (59, 59′) and can be removed therefrom without tools. The invention also relates to an automatic firearm equipped with such a chambering device (1).
