The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). [2] It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.
The XM214 was first developed for aircraft applications. Later General Electric developed it into a man-portable weapon system, known as the GE Six-Pak. The complete Six-Pak system weighed 85 pounds (38.5 kg) with 1,000 rounds of ammunition, comparable in weight to some heavy machine guns. The basic gun in the Six-Pak weighed 27 pounds, or 12.2 kg.
It is also the basis of the GPU-2/A gun pod, which incorporates the cannon, a battery and electric drive motor, and 300 rounds of linkless ammunition. In the Cobra, the weapon is supplied with a magazine of 700 linked rounds, with a total capacity including feeder system of 750 rounds. It has a cyclic rate of fire of 730+-50 rounds per minute.
The Vulcan's rate of fire is typically 6,000 rounds per minute, although some versions (such as that of the AMX and the F-106 Delta Dart) are limited to a lower rate, and others (A-7 Corsair, F-15 Eagle) have a selectable rate of fire of either 4,000 or 6,000 rounds per minute. The M61A2's lighter barrels allow a somewhat higher rate of fire ...
The cartridges measure 11.4 inches (290 mm) in length and weigh 1.53 pounds (0.69 kg) or more. [8] [13] GAU-8 mounted in A-10. The Avenger's rate of fire was originally selectable, 2,100 rounds per minute (rpm) in the low setting, or 4,200 rpm in the high setting. [2] This rate was later changed to a fixed rate of 3,900 rpm.

Electronic firing refers to the use of an electric current to fire a cartridge instead of a centerfire primer or rimfire primer. [1]In modern firearm designs, a firing pin and primer are used to ignite the propellant in the cartridge which propels the bullet forward.
Rate of fire may also be affected by ergonomic factors. For rifles, ease-of-use features such as the design of the bolt or magazine release can affect the rate of fire. For artillery pieces, a gun on a towed mount can usually achieve a higher rate of fire than the same weapon mounted within the cramped confines of a tank or self-propelled gun ...
A minigun with a belt of separate firing chambers also exists. [9]The Multi-shot Accessory Under-barrel Launcher is an electronically fired, 12-gauge shotgun for use as an accessory weapon to a range of weapons, such as the M4 or M16 rifle, or as a stand-alone 5 shot weapon, providing a range of lethal (buckshot and slug) and non-lethal (blunt impact, door breaching, and frangible) munitions ...
