M134 미니건(Minigun)은 M61 벌컨 기관포를 토대로 소형화 제작한 7.62 × 51 mm NATO탄을 사용하는 회전식 다총열 중기관총이다.
주로 헬기와 전투기,군함등 차량에 부착되어 쓰인다. M134의 후속작인 M13D 미니건도 있다.미니건을 사람이 직접 들고 서서 쏘면 반동으로 인해 넘어질 수도 있다고 한다.

The M134 Minigun is a 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 "Mini" in the name is in comparison to larger-caliber designs that use a rotary barrel design, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" for the use of rifle ammunition as opposed to autocannon shells.
"Minigun" refers to a specific model of weapon that General Electric originally produced, but the term "minigun" has popularly come to refer to any externally powered rotary gun of rifle caliber. The term is sometimes used loosely to refer to guns of similar rates of fire and configuration, regardless of power source and caliber.
The Minigun is used by several branches of the U.S. military. Versions are designated M134 and XM196 by the United States Army, and GAU-2/A and GAU-17/A by the U.S. Air Force and U.S. Navy.

The ancestor to the modern minigun was a hand cranked mechanical device invented in the 1860s by Richard Jordan Gatling. Gatling later replaced the hand-cranked mechanism of a rifle-caliber Gatling gun with an electric motor, a relatively new invention at the time. Even after Gatling slowed the mechanism, the new electric-powered Gatling gun had a theoretical rate of fire of 3,000 rounds per minute, roughly three times the rate of a typical modern, single-barreled machine gun. Gatling's electric-powered design received U.S. Patent #502,185 on July 25, 1893.[3] Despite Gatling's improvements, the Gatling gun fell into disuse after cheaper, lighter-weight, recoil and gas operated machine guns were invented; Gatling himself went bankrupt for a period.[4]
During World War I, several German companies were working on externally powered guns for use in aircraft. Of those, the best-known today is perhaps the Fokker-Leimberger, an externally powered 12-barrel rotary gun using the 7.92×57mm Mauser round; it was claimed to be capable of firing over 7,000 rpm, but suffered from frequent cartridge-case ruptures[5] due to its "nutcracker", rotary split-breech design, which is fairly different from that of conventional rotary gun designs.[6] None of these German guns went into production during the war, although a competing Siemens prototype (possibly using a different action), which was tried on the Western Front, scored a victory in aerial combat.[5] The British also experimented with this type of split-breech during the 1950s, but they were also unsuccessful.

The GAU-19/A (GECAL 50) is an electrically-driven, three-barrel rotary heavy machine gun that fires the .50 BMG (12.7×99mm) cartridge.
.
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 1.7kN, 2.2kN or 2.8kN depending on firing rate. In January 2012, General Dynamics announced they would be delivering a new version designated GAU-19/B. It provides the same firepower in a lighter platform, weighing 48 kilograms (106 lb) and optimized for a firing rate of 1,300 rounds per minute and an average recoil force of 2.5kN.[1] Both variants can be configured for an ammunition capacity of 500-1,200 rounds. Both variants are reliable to 40,000 mean rounds between failure.

The GECAL 50 was first manufactured by General Electric, then by Lockheed Martin, and now by General Dynamics. Design work began in 1982. Early prototypes had six barrels, but a three-barreled configuration is now standard. The GAU-19/A was originally designed as a larger, more potent version of the M134 Minigun. Due to the loss of nine helicopters in Grenada, GE started building prototypes of the weapon in both a three-barreled and a six-barreled configuration. The six-barreled version was designed to fire 4,000 rounds per minute, and could be adapted to fire up to 8,000 rounds per minute. The GAU-19 takes 0.4 seconds to reach maximum firing rate.[2] Soon it was recommended as a potential armament for the V-22 Osprey.[3] The magazine would be located underneath the cabin floor and could be reloaded in-flight. However, plans to mount the gun were later dropped.[4] In December 1992 the US Navy issued a letter of qualification for GAU-19/A integration and use on naval aircraft. In 2005, the GAU-19/A was approved to be mounted on the OH-58D Kiowa helicopter. It also could have been used on the Army's now cancelled ARH-70.[5]
