  • Patent number: 11435152
    Abstract: The invention relates to a firearm comprising one or more retractable loading system elements, specifically at least one from a loading device, breechblock carrier, or slide. These each follow a trajectory when retracted. The firearm also comprises one or more reference elements, which indicate such a predetermined position of the loading system elements along their respective trajectories, at which the chamber is opened, such that a cartridge potentially located in the chamber can be seen and/or felt, but is not ejected. The predetermined position of the loading system element is distanced to possible positions for disassembling the firearm, and the one or more reference elements are formed such that they ensure that the loading system elements can travel freely along their respective trajectories when the safety for the firearm is either on or off.

  • Patent number: 9052155
    Abstract: A firearm includes a cocking lever, a shoulder-stock receptacle and a shoulder support having a shoulder stock configured to be joined by a connector to the shoulder-stock receptacle. A shoulder-stock adjuster is configured to adjust a position of the shoulder stock relative to the shoulder-stock receptacle along an adjustment axis. A cheek rest is mounted via a bearing on the shoulder stock so as to be movable in a direction parallel to the adjustment axis. A stop is disposed on the shoulder-stock receptacle so as to limit a movement path of the cheek rest towards a front of the firearm. At a position of the cheek rest defined by the stop of the shoulder-stock receptacle, the cocking lever does not collide with the cheek rest, even in a completely retracted state.
