A breechblock for an automatic firing weapon comprising a breechblock housing having a bore in which there is connected a weapon barrel,a breechblock body is displaceably arranged in the breechblock housing. The breechblock body is equipped with at least one blocking body by means of which the breechblock body can be locked with the breechblock housing. The blocking body bears against a rest or arresting surface of a locking body inserted into the breechblock housing. The locking body is of substantially sleeve-shaped configuration and is equipped at its rear end with a cut-out or notch extending transversely with respect to the lengthwise axis of the weapon, the side walls of which form the arresting surfaces. The locking body is arranged coaxially to the weapon barrel in the aforementioned bore of the breechblock housing, and it bears with its rear end surface at a shoulder of the breechblock housing and at a rear end surface of the weapon barrel.
