Abstract
For a space saving and shock free breech block for an externally driven automatic weapon, a control roller 10 includes two camming discs which offset by 180.degree. with respect to one another in a symmetrical manner and arranged one behind the other, so as to continuously rotate in the same direction as the control roller. For the displacement of two locking bars disposed on opposite sides of the breech block 9 in a direction transverse to the direction of movement of the breech block, respective slide members are arranged between the breech block guide path axis and the control roller 10. Each slide member grips around one of the camming discs by meane of a U-shaped pocket and transfers the transverse movement of the associated camming disc to an associated one of the locking bars for locking and unlocking breech block 9 in a form locking manner.
