@DarthKenobi0: I fired a friend's fully automatic M16A1 and I had no problem putting multiple rounds center mass on a dog target at about 100 yards; didn't have much more range to work with. I was firing from the prone on that one, but it's not that bad at all from the kneeling or offhand, either. I mean, look how small the rounds are; you're basically firing .22s with some nuts behind 'em. As an aside, if he was having trouble holding it steady, he probably discharged the entire magazine. Short, controlled bursts - cliche to hear, but effective.
