That would be a very awkward way to do forced air cooling when you don't even take advantage of the Gatling setup for a blistering rate of fire. If you look at something like an old Lewis gun, it has a hollow shroud over a single barrel, and some radiator fins running along the barrel, the gas escaping the muzzle after the bullet forcibly pulls in cool air from behind the shroud and runs it along the barrel.

And that's an old WW1 era clunkerfucker, you can apply a similar principle to basically any automatic.
