The M134 Minigun is a multiple barrel machine gun capable of firing up to 6000rpm.
The M134 is commonly referred to as the Minigun because of its relatively low caliber compared to weapons such as the M61 Vulcan from which it is derived as it was intended as the smallest gun used on an aircraft 'Mini gun'. This weapon gets its design from the larger M61 Vulcan. It is scaled down to fire 7.62 x 51 mm NATO rounds. It is known for its high rate of fire and is most commonly used mounted in aerial vehicles such as helicopters and aircraft.
An Iranian copy of the M134 exists as the Akhgar machine gun and is used on light vehicles.
