In this video by The Forgotten Weapons, Ian features a General Electric M134 “Minigun”. The Minigun is a six-barrel rotary machine gun with a high rate of fire. It is essentially an electrically-powered Gatling gun, in the sense that the conceptual operation of the gun is identical to Richard Jordan Gatling’s original creation. What has changed with the Minigun, however, is the chambering. The Minigun is in 7.62 NATO.
