The M-134 Minigun is a real-life multi-barrel 7.62 mm machine gun which utilises Gatling-style rotating barrels, and is capable of firing at speeds of up to 6000 RPM (rounds per minute). It features prominently in "Chuck Versus the Pink Slip", when not only is it seen on occasion throughout the episode, but Casey uses it to rescue Chuck and Sarah at the end of the episode. He assaults a Ring base in Mexico with it via helicopter before landing and extracting the pair.
