Abstract:
1. A machine gun having a main housing, a rotor assembly supported by said main housing and adapted for being electrically rotated, a plurality of bolt assemblies attached to said rotor assembly, a like plurality of barrels attached to said rotor assembly, and a helical track extending longitudinally within said main housing for driving said bolt assemblies in forward and rearward directions in response to rotation of said rotor assembly, comprising: a top cover removably attached external to a portion of said main housing, said top cover including an aft camming portion of said helical track on an underside thereof; and a safing blade removably hingedly attached to said top cover intermediate a rearward end and a forward end of said top cover, said safing blade including a forward camming portion of said helical track on an underside thereof, said safing blade being adapted for rotation, while said top cover is attached to said main housing, between a closed or armed position in which said bolt assemblies follow said forward camming portion of said helical track to facilitate firing of the gun and an open or safing position in which said forward camming portion of said helical track is removed to thereby prevent firing of the gun; said aft camming portion of said helical track being operative, when said top cover is attached to said main housing and said safing blade is in said open position, for driving said bolt assemblies in response to electrical rotation of said rotor assembly to eject any live cartridges residing in said bolt assemblies without thereby damaging said bolt assemblies.
