Haven't watched the videos, but some have said it sounded like AKs.
Look at this video and tell me it doesn't sound like shots are coming from 2 guns. Or is it an echo?
Or this.

I would go with echo.
Mandalay Bay isn't straight across, it has a curve and would easily cause that noise.
someone claimed countersniper ops experience, and that his opinion was single shooter based on watching the vids

idk
Idk man, to me it sounds like at least 2 guns were firing at the same time. Who knows.
Good comment on pol:
It wouldn't be hard to get that many casualties when firing directly into an unprotected crowd that big. He fired a lot of shots.
When I first heard it I was thinking either the supersonic bullet sound issue as described below or also sounds reflecting off of nearby buildings.
I also tend to agree with those who think it was a belt-fed mg, going by the sound.
At first, I thought it was either a B.A.R. or a belt fed M-1919 machinegun because of the slow cyclic rate of automatic fire. But, when I found out that at least several of his rifles had bumpfire stocks, that explains the slower cyclic rate of fire. It takes longer between shots with a bumpfire stock because of the way it works.
