    摘要： Delayed action magazine-based self-loading firearm with gas piston action. Delay action prevents the movement of the self-loading firearm's slide and lock during the actual shot and will keep them closed. The construction of the delayed action stores the energy from the powder gas either mechanically or pneumatically, to be used later for the operation of the firearm's load-lock mechanism. The delayed action mechanism of a delayed action firearm consists of the body (E) and a guide (C) with its openings (D) placed inside it, through which the high-pressure powder gas escapes through the firearm's barrel (A) onward to the gas piston (F), which moves pierced by a pole (H), with the pole (H) being attached to the bottom piece (I). A spring (G) may be connected to the pole (H), with the pressure of the powder gas compressing either the spring (G) or alternatively the air by the gas piston (F) against the bottom piece (I). The retainer (K) stops the gas piston (F) into its back position leaving the spring (G) or air into compression. Through the action of the shooter or a separate automatic mechanism on the releaser (M) the bottom piece (I) is allowed to dash backwards with the help of the spring (G) or air. The bottom piece (I) is fixed to the firearm's slide (O), which uses the firearm's load and lock mechanism to perform the cartridge case removal and loading actions.

    摘要： A semiautomatic or fully automatic firearm that includes a barrel, the rear barrel end whereof is in the form of a cartridge chamber into which a cartridge can be inserted, a breech body which is arranged such that it can move in the longitudinal direction between an open position, which releases the cartridge chamber for the reloading of a cartridge, and a closed position which closes the cartridge chamber, wherein the breech body closes the cartridge chamber at the rear in the closed position and is used as a support for the cartridge case of the cartridge, wherein the firearm has a mass simulation body which is in force-fitting engagement with the breech body, in particular a mass simulation body which is rigidly connected to the breech body, the mass simulation body being formed at least in part from a magnetizable or a magnetic material.

    摘要： A reciprocating bolt assembly has delayed blowback and a firing pin block. Features prevent out-of-battery firing, when the bolt assembly is not fully engaged to the firing chamber or barrel face, a movable member within a bolt body functions as a blocking member that blocks the firing pin and prevents the firing pin from striking a cartridge. In embodiments, the firing pin has two stop portions that the movable member can engage depending on the cycle status of the firearm. A reverse cam mechanism associated with the firing pin blocking provides a resistance to and delays blowback.

    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.
