>>I don't know what you mean by "effective". I've seen videos where the same weapon is fired with a lot higher rpm than that.

The AR-15 was designed for automatic fire, and the barrel can sustain high rpm (when enabled) even when super hot, although that may damage the lining in the long run. I don't think that criminals/mass shooters are concerned with that detail.
