ABSTRACT:
A breechblock for an automatic firing weapon wherein at the breechblock having a control element and a breechblock head which can be locked at the breechblock housing the locking elements are specially designed. At a front part of each locking element containing the pivot axis of such locking element there is provided a locking surface and at a rear shoulder or projection of each locking element there is provided a support surface beneath which there can engage the control element. Since the locking surface is disposed forwardly with respect to the end of the support surface the path of movement of the breechblock is shortened, and thus, the firing cadence or speed is increased. Furthermore, at the locking elements there are present more favorable force conditions.
