Abstract: A breech system having a weapon barrel which is mounted in a cradle such that it can be moved from a rest position to a recoil position, said breech system comprising a base piece, comprising a breech wedge which can be moved between a closed and open position, a breech mechanism which is attached to the base piece and a guide piece which is fixed to the cradle and has a guide element, wherein the guide element has an actuating element for actuating the breech mechanism, wherein the breech mechanism has a lever mechanism that can be actuated by the actuating element, wherein the breech mechanism has a locking lever which is coupled to the lever mechanism, and wherein the breech wedge can be locked in the open position by the locking lever.

Abstract: A breech block, in particular wedge breech block, having a breech end and a breech wedge. The breech block includes an opener shaft with a rotationally coupled opening lever and an ejector system for pulling out cartridge cases or cartridge bases from the breech block. The ejector system includes at least one ejector and at least one ejector lever. The ejector lever is rotationally movably mounted on the opener shaft and the ejector system has at least one transmission element which transmits a rotational movement of the opening lever to the ejector lever.

Abstract: The invention relates to a gun barrel mounting for a gun barrel, comprising a cradle with at least one gun mounting for mounting the gun barrel and a base part that can be connected to the gun barrel.
