you could trivially end up needing to do that shit with any MG tho, firing until the barrel glows is a literal thing that is sometimes done, the sergeants i got my LMG training from made a point out of always bringing a old, basically worn out barrel and running it for long enough that it would glow to make the point of A : it doesn't take long to get to that point. B: this is how it actually looks, so keep a eye on the fucker and C : this is how you handle it, and you just wrecked the barrel in the process, dumbo.
