Abstract
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.
