I did the machine gun score you hear in "The Green Beret", a John Wayne Movie.
Couldn't hear for two weeks, but those precision bursts of 3, bursts of 4, bursts of 6 ~ that's me. It's not just tattitatat.
If need be I could have dismantled wood frame houses with a few hundred rounds.
Although I do believe the government owes it to me and should provide me with my very own M60 and a couple of pallets of ammunition, I don't believe you can be trusted with one of those devices. They really are too much for the untrained.
It seems ridiculous, but the logic is the same.
