The M75/GAU-25 Machine Gun is a twin-barreled recoil-operated 7.62x51mm machine gun developed by the Paternian Republic for use on helicopters and light aircraft. It employs the unique Gast-system, where the firing of one barrel operates the action of the other. This allows the gun to attain a rate of fire of 3,000 rounds per minute. While half the potential rate of an M134/GAU-17 Minigun, it is lighter, does not require any external power to operate, are easier to load and service, and does not require a delinker. In combat, the gun proved very popular due to its reliable operation, high rate of fire, and simple design. The most common application was as a door gun for helicopters. Many unofficially made their way to ground units, who employed them on vehicle-borne pintle mounts or fixed tripod mounts. Such power of these weapons that the presence of the weapon was enough to dissuade attacks. These guns were either traded from helicopter units or salvaged from wrecked aircraft. This example employs standard aircraft gunner iron sights, although reflector sights are also available. The central handle is for cocking the guns.

@MrMecha Just scale it up to autocannon caliber and you'll be walking through heavy mechs like Neo walks through an office building lobby.
Minus throwing away thousands of dollars worth of firearms as if they magically grew from trees instead of reloading them.
@PINK That's basically a GSh-30.
In fact, that is what the GSh-30 is. A 30mm autocannon based on the Gast principle.
Soviet engineers, like their western counterparts, wanted a compact, rapid-fire cannon armament for jet fighters. However, they didn't want an externally-operated system such as a revolver cannon or Gatling-style weapon.
In their experience, gas-operated revolver cannons were quite complex (see ShVAK cannon) and Gatling-style weapons were heavy.
Then they found the Gast principle, which was perfect. Rapid-fire, reliable, simple, robust, relatively light, and most importantly, didn't need an external power source to operate.
@Pilotmario Can we have a 30mm variant?
@bjac0 Thanks!
@PINK Interested in the gun? It's really an underrated operating principle.
Pretty much everyone that tested Gast guns says its simple, robust, reliable, and very quick firing.
