The resulting weapon, designated M134 and known as the "Minigun", could fire up to 6,000 rounds per minute without overheating. The gun has a variable (i.e. selectable) rate of fire, specified to fire at rates of up to 6,000 rpm with most applications set at rates between 3,000 and 4,000 rounds per minute.
The ability to fire the 5.56 mm round used by the M16 rifle was the major selling point for the Microgun. With a fast-firing gun using standard rifle ammunition, the US Army and US Air Force showed interest for use of the XM214 on aircraft, helicopters, and armored vehicles.
The multiple barrels provide both a very high rate of fire—around 100 rounds per second—and contribute to prolonged weapon life by minimizing barrel erosion and heat generation. [9] The average time between jams or failures is in excess of 10,000 rounds, making it an extremely reliable weapon. [ 10 ]

The M134 Minigun fires 7.62mm ammunition at 3,000 to 4,000 rpm. The M3P Machine Gun, an M2 variant with a higher rate of fire mounted on the Avenger Humvee. The GAU-19, a rotary gun that fires .50 caliber ammunition. Mounted on Humvees and helicopters. The M230 Autocannon fires 30×113mm ammunition at 625 rounds per minute.
The GAU-19/A is designed to accept standard NATO .50 caliber M9-linked ammunition. The rate of fire is selectable to be either 1,000 or 2,000 rounds per minute. The Humvee armament kit version fires at 1,300 rounds per minute. The average recoil force when firing is 382 lb/ft, 495 lb/ft or 629 lb/ft depending on firing rate.
In order to develop a weapon with a more reliable, higher rate of fire, General Electric designers scaled down the rotating-barrel 20 mm M61 Vulcan rotary cannon for the 7.62×51mm NATO ammunition. The resulting weapon, the M134 Minigun, could fire up to 6,000 rounds per minute without overheating. The gun has a selectably variable rate of fire ...
The gun fires at 3,000 rounds per minute in short bursts of 10, 30, 60, or 100 rounds, or it can fire in continuous fire mode at a rate of 1,000 rounds per minute. [4] A linkless feed system is used. Its 20x102mm round gave it a low effective range of only 1,200 meters (3,900 ft), and its standard air-defense load of HEI-T rounds would self ...
