The M134 minigun is a weapon that no enemy ever wants to face. Equipped with six rotating barrels that can unleash fifty rounds per seconds, it delivers devastating firepower. Too powerful to handle manually, this minigun is typically found mounted on helicopters, vehicles and ships.
The M134 uses standard 7.62-mm rounds fed to the gun in linked belts. Magazines for this gun have capacities ranging from 500 to 4,000 rounds, meaning the warfighter can engage the enemy longer without the need to reload.
This minigun uses six revolving barrels to produce a fixed rate of fire of 3,000 or 4,000 shots per minute. When the gun is mounted to aircraft, it typically has a standard barrel, while a heavy version is found when it is mounted to ground vehicles, ships, and heavy lift helicopters.
The heart and soul of the M134 is the rotor, which can be made of either lightweight titanium or carbon steel. It contains the six gun bolts and barrels that chamber, fire, extract and eject six rounds per revolution (50 rounds per second).
