Some are saying flash suppressors can’t completely hide muzzle flash. Maybe that was true from when they were in the military, but today, many brands virtually hide all light coming out of the barrel — including full auto. It can barely be seen from 10 feet away! Here is video proof! Great song in the first video, by the way.
Some of the videos below show how giant the flame coming from the barrel of an AR is when not flash suppressed. A friend told me: there were no reported flash suppressors or hiders found on any of the guns in the Paddock room. If Paddock was firing from Mandalay Bay, all of the videos should show it. But there is nothing.
The shots had to come from elsewhere: helicopters, rooftops, and/or the ground, from guns that had flash hiders.

Manufacturer says: “Specially angled flutes hide nearly 100% muzzle flash, even during full-auto fire, by dissipating gas and retaining unburned powder for increased residual burn.”

The M60 machine gun is like the steady, belt fed, gun sounds that many think we hear in the Vegas videos. Full auto and no flash seen!
