Yes it does, because you could play just the audio of the cyclic rate of fire of the Vegas shooting to any blindfolded current of past US military member who has been exposed to the sound of a 240 Golf or 240 Bravo (depending if you were Army (240 Bravo) or Marine (240 Golf)) will tell you it is the exact same belt fed 30 caliber machine gun. The reason why they would tell you that is because it is the same gun. I am sure the Vegas shooting audio of the shooting has the same exact verifiable signature as those weapons.

The first time I heard the audio, instantaneously I knew what gun the shots came from, reason being I am an ex-Marine and that sound is permanently imprinted in my mind. I can tell the difference immediately and identify without question between M2A1, M249 Saw and M240 Golf and M16. Any past or current US Army or US Marine would tell you the same thing.
