Firing a 100 round magazine non-stop through an AR-15 will cause the gas tube to glow cherry red and start to melt. Continuous 30 round bursts will make the gun so hot it will malfunction in short order. It takes much longer for the gun to cool than it does to fire the magazine. That is the likely reason the Vegas shooter had a dozen rifles. He was alternating them while they cooled.

I’m still looking for an explanation as to why someone would need a gun that could fire that many rounds in that short a time. That’s really the question I want asked if there are potential hearings:

What possible need does an average person have for a gun, modified or not, that is capable of firing 100 rounds per minute? 75 rounds per minute? 50 rounds per minute? 30 rounds per minute?
