The invention relates to a bolt stop for an automatic firearm comprising a bolt stop lever that can be moved between a release position and a catch position, and a locking device that can be moved between a standby position and a locking position, for selectively securing the bolt stop lever in the release position, wherein the locking device is disengaged with the bolt stop lever when in the standby position, and is engaged in with the bolt stop lever when in the locking position, the bolt stop lever deactivated in the locking position.

A weapon which has a modular design. The weapon is subdivided into weapon-specific modular assemblies which are designed as carrier units of the components. The modular assemblies include a weapon housing into which a breech system of the weapon and a striking mechanism is provided, a weapon cradle that connects with the weapon housing, and a weapon barrel module. The modular assemblies are connected to each other by rails and guides, by binders and holders, by pins, or by bolts and quick release fasteners.

The purpose of the invention is to ensure that the delaying roller remains an integral part of the breech mechanism after removing the breech mechanism from the fire arm. The automatic firearm breech mechanism featuring a breech (3), a breech carrier (4) and a delaying roller (2) that is positioned between the rear vertical wall (32) of the breech (3) and the front vertical wall (41) of the breech carrier (4), moving vertically, while between the rear vertical wall (32) of the breech (3) and the front vertical wall (41) of the breech carrier (4) a modified cage (8) surrounding the delaying roller's (2) working area is placed. The cage (8) created from a strip bent into the shape of the reversed letter U, featuring an opening (82) located on its horizontal wall (81), while its vertical walls (83) are fitted with a slide stop (84) at both ends.

A cocking device for a firing pin spring of a firing pin of a weapon, the firing pin being integrated into a breech. This firing pin spring is cocked during the pre-run of the control slide, by means of a cocking slide on the weapon, said cocking slide having a cocking curve, in which a pin of a cocking rocker is engaged.

Gun (1) comprising a gun frame (2); a barrel (4), supported by the gun frame (2), proximally delimiting a firing chamber (6) extending along a longitudinal axis (X); a slide (8), translatable longitudinally in relation to the barrel (4) between a forward configuration wherein the slide closes the firing chamber (6), and a rearward configuration wherein it is distanced from a proximal mouth (12) of the firing chamber (6), to open the latter; wherein orientation of said chamber (6) is substantially parallel to said axis (X) in the forward configuration and in the rearward configuration; and a locking device (10) mechanically locking barrel (4) and slide (8) to each other in the forward configuration, and that in the rearward configuration is guided transversally in relation to the barrel (4) for unlocking the slide (8). Slide (8) and locking device (10) delimit arched locking surfaces (14, 16) that in the forward configuration are coupled with each other for locking the slide (8), and that in the rearward configuration are mutually spaced in a transversal direction for opening said chamber (6).
