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.
- Casey complains near the start of the episode that he was never given the opportunity to use the gun, which is clearly why he chose to employ it when rescuing Chuck and Sarah.
- In the episode, Casey claims the gun fires at 3400 RPM. The maximum speed of a real-life practical application of the gun is around 4000 RPM, making this figure plausible. However, some modified M-134s are able to run as high as 6000 RPM for short amounts of time.
