Have you ever shot one? Better yet, shot one from long distances? It is incredibly hard to keep it on target on full auto and nigh unto impossible to do that with a bump fire stock. To the degree that the whole gun is jumping in your hands (for a strong person), even having a scope becomes totally worthless. It's just in the way and doing you no good. Not to mention bump fire stocks are very physically demanding. This guy was no athlete.

So it's not too physically demanding if a 100 lb girl can handle it without issues.
This old guy can handle it OK-

And throw in the fact that the Vegas guy wasn't aiming at anything specific, he had a whole parking lot to aim at.
