THE INVENTION RELATES TO A DRIVE HAVING A QUICK STOP MECHANISM FOR A BREECH (3) OR BREECH CARRIER WHICH CAN BE AXIALLY ADJUSTED RELATIVE TO A WEAPON BARREL (1), SAID DRIVE COMPRISING AT LEAST ONE MOTOR OR THE LIKE, TWO COUNTER-ROTATING CHAINS (6) AND SPROCKET WHEELS (5) AROUND WHICH THE CHAINS (6) ARE GUIDED. ENGAGING CAMS (7) AND CONTROL CAMS (8) ARE INTEGRATED INTO THE CHAINS (6). A SLIDE (11) IS MOUNTED ON TWO GUIDE BOLTS AT THE BOTTOM OF THE BREECH (3) SO AS TO BE DISPLACEABLE AT A RIGHT ANGLE TO THE DIRECTION OF FIRE AND HAS A GROOVE (12) INTO WHICH THE ENGAGING CAMS (7) OF THE RESPECTIVE CHAINS (6) ENGAGE TO ENTRAIN THE BREECH (3) IN A FORWARD OR REVERSE MOTION IN RELATION TO THE DIRECTION OF FIRE. THE ENGAGING CAM (7) TRANSPORTING THE BREECH (3) FORWARDS IS DISPLACED OUT FROM THE GROOVE (12) WHILE THE CONTROL CAM (8) OF SAID CHAIN (6) DISPLACES THE SLIDE (11) SIMULTANEOUSLY TO IS CENTER POSITION VIA ITS ASCENT RAMP (13), THEREBY ALLOWING THE REST PERIODS OF THE BREECH (3) IN THE FORWARD END POSITION. ONCE THE SHOT IS FIRED, THE SLIDE (11) IS DISPLACED FROM THE CENTER POSITION TO THE OTHER WEAPON SIDE WHEREAS IT REMAINS IN THE CENTER POSITION WHEN NO SHOT IS FIRED SO THAT NONE OF THE ENGAGING CAMS (7) CAN ENTRAIN THE BREECH (3) BACKWARDS.
