Host Paul Shull is on a mission to fix and fire an electric M-134 minigun from the Vietnam War, a six-barreled behemoth that could fire up to an astonishing 6,000 rounds per minute. It's the fastest machine gun ever to see action, but piecing this vintage weapon back together is going more slowly than planned. Join Paul as he tracks down the missing parts he needs to complete the rebuild while investigating the evolution of the machine gun. Then buckle up as he goes airborne to test his refurbished minigun in a vintage AH-6 attack chopper.
