Abstract
This disclosure relates to an automatic weapon having a breech mechanism driven in reciprocation by an external motor and equipped with a device to keep the breech mechanism from moving from the advanced or forward locked position in case of a hangfire. If a 'shot departure' sensor fails to sense the departure of a shot a spring projects bolts into the path of the breech mechanism and locks it at the start of its recoil stroke.
