Minigun M134迷你炮机枪

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) which can also fire at a high-sustained rate. It features Gatling-style rotating barrels 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-millimeter M61 Vulcan, and "gun" for the use of rifle caliber bullets instead of shells used by an autocannon.
