Gatling gun refers to a gun with multiple firing pins and breeches connected to multiple rotating barrels. Each barrel fires a single shot as it reaches a certain point in the cycle after which it ejects the spent cartridge, loads a new round, and in the process, cools down somewhat.The gun was designed by the American inventor Dr. Richard J. Gatling, in 1861 and patented in 1862.When used in Vietnam, the Minigun was nicknamed "Puff the Magic Dragon" because it fired red tracers that gave the appearance of breathing fire.This Gatling gun was created by Dillon Aero and mounted to a brand new SUV to convey its ease of operation and speed of implement. With the cycle rate factory set at 3900 rounds a minute, I would mind having one for my very own.
