摘要： A weapon system that includes a breechblock, which is formed at least by a breechblock carrier and a breechblock head, the breechblock carrier being designed so as to carry the breechblock head. To achieve the fact that forces acting upon the breechblock drive during the unlocking of the breechblock and the withdrawal of a cartridge casing are minimized or even eliminated, the breechblock head is freely movable relative to the breechblock carrier. To separate the breechblock with a breechblock drive of the weapon system during the recoil of the recoiling masses of the weapon system, a device is designed in such a way that a mechanical separation takes place between the breechblock and the breechblock drive during the recoil of the recoiling masses of the weapon system. During the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is reestablished via the device.

摘要： A suppressed pistol has a breech block and a slide mounted on a frame. The breech block and slide are separate pieces, movable relatively to one another and the frame. A link extends between the breech block and the frame. The link carries a cam and a cam follower. The cam follower on the link engages a cam on the frame, the cam on the link engages a cam follower on the slide. Action between the cams, cam followers and the link causes separation between the breech block and the slide during operation of the pistol. The suppressor includes a container having baffle plates with truncated cones defining openings offset from the geometric centers of the baffle plates.

摘要： A firearm includes a moveable bolt assembly that absorbs energy associated with the discharge of the firearm. An energy absorbing mechanism within the bolt assembly may include a dampening spring that provides recoil energy dissipation. With this arrangement, one or more actuators may be provided that are operative to compress the dampening spring with respect to the bolt assembly in response to the discharge of the firearm.

摘要： A breechblock for an automatic firing weapon comprising a breechblock housing containing a breechblock head displaceable in the breechblock housing. There is also provided at least one movable blocking body by means of which the breechblock head can be locked in a firing position with the breechblock housing. A spring-loaded control element is arranged to be displaceable in the breechblock housing, this control element containing a control surface by means of which there can be positionally adjusted the blocking or locking body. In the breechblock head there is arranged a locking bolt which can be shifted into a recess of the control element. By means of the locking bolt the breechblock head, which is unlocked from the breechblock housing, can be coupled with the control element, and play is present between the control surface and the blocking body and by means of which, prior to reaching the firing position of the breechblock head, there is uncoupled the control element.
