Is the minigun in predator a real weapon?
Gemini
Yes, the M134 Minigun is a real weapon, but the handheld version used in Predator (affectionately called "Ol' Painless") is completely impractical in real life. [1, 2, 3]
The real-life M134 is a six-barreled rotary machine gun used by the U.S. military. However, in reality, it cannot be carried and fired by a person like it is in the movie. [2, 3, 4, 5, 6]
Key differences between the movie prop and the real weapon include:
- Weight and Power: Real miniguns weigh around 85 pounds and require a heavy external power source (such as an electrical cable or massive battery) to spin the barrels. [3, 5, 7]
- Rate of Fire: A real M134 fires 2,000 to 6,000 rounds per minute. In the movie, the prop's firing rate was drastically slowed down to 1,200 rounds per minute so that actor Jesse Ventura could manage the recoil and to conserve blank ammunition on set. [2, 3, 5, 8]
- Ammunition Capacity: Firing the gun at full speed drains thousands of rounds in seconds. Carrying enough ammo on foot to sustain a firefight is practically impossible. [1, 5, 6]
- Hollywood Legacy: Because it is too heavy and power-hungry to be shoulder-fired, the weapon in Predator relied on a hidden off-screen cable for power and was bolted to a modified harness. The exact same prop gun was later used by Arnold Schwarzenegger in Terminator 2: Judgment Day. [3, 8, 9, 10, 11]

So we should assume that in-universe the minigun has some kind of as-yet-developed power supply and probably uses
