The M134 Mini Gun is the baddest machine other than it’s cousin the 40mm GAU-8/A Avenger gun on the A-10. There is nothing mini about the M134 though. It fires the 308 NATO or 7.62 x 51 and at a staggering 4,000 rounds per minute. It is absolutely devastating in the field. It was used in Vietnam and changed the war. The Mini Gun has 6 rotating barrels and an electric motor that spins the barrels. It is incredible to watch in action.
