It would happen too, just not after a handful of seconds.
Miniguns use multiple barrels so that the barrels don’t overheat. But then they increase the fire rate significantly. In Vietnam, a common machine gun mounted in the door of a helicopter was the M60 which has one barrel and fires at about 600 rounds per minute. Door mounted miniguns like the M134 have 6 barrels but fire at up to 6000 rounds per minute. So, the barrels would actually overheat even faster than an M60s would at the full rate of fire despite having multiple barrels. Of course, you couldn’t actually shoot at 6000 rounds per minute while carrying one of those on foot, the recoil would not be possible to manage.
In their defense, gun barrels getting red hot from use is cool as fuck.
This is a real thing. Even LMGs generally have multiple barrels that you have to change out during sustained fire.
