The M134 Gatling Gun, sometimes known as the Minigun, is a 7.62mm multibarrel machine gun with a high rate of fire employing gatling-style rotating barrels with an external power source.



The M134 was developed as a method of scaling down the M60 Vulcan cannon yet still retaining its firepower. It saw use in the Vietnam War via attack choppers such as the UH-1D "Huey" Iroquois.

During the 1974 Peace Walker Incident, Big Boss and the Militaires Sans Frontieres procured design specs for the M134 Gatling Gun after capturing a LAV-C Custom. Their R&D, including some M134 design specialists, then developed their own M134 gun.

Behind the scenes

"An unholy terror of a weapon that spits out thousands of bullets per minute from its six rotating barrels.
Its destructive power is the stuff of legend. However, the system's enormous weight makes handling it a nightmare.
If you think power is everything, then this is the gun you've been looking for.
