The entire gun installation weighs an incredible 1,830 kilograms. Even with such a huge caliber, the 7-barrel weapons rate of fire is an incomprehensible 3,900 rounds per minute. But of course, we're talking about the M134 minigun, the absolute record holder of rapid fire. In just one second, its six barrels can fire 100 bullets. It's scary to even imagine being in the M134's line of fire. The M134 minigun is widely recognized as the greatest machine gun of all time and has made regular appearances in Hollywood movies, starting with the legendary Predator. In real life, the M134 minigun's red-hot barrels look even cooler. Its core consists of four miniguns that can fire up to 12,000 rounds per minute.
