The extremely powerful quadruple M134 Minigun in action on a shooting range during the Big Sandy Shoot event held annually near Phoenix, Arizona, United States.
The Big Sandy is the largest machine gun shoot in the US.
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire. It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.
