Full auto, pulling singles, doubles and triples is easy with practice.
m16 burst is stupid, you pull a double and the next pull is a single until the cam resets. And with 9mm, I always like to pull a couple three triple taps, a good 10rd burst and punch out the center of a target, then some triple taps u til the mag runs out, or just let it eat all 20 or so. burst only people might go "he has a binary", a half a mag people go "I wish I was that guy"
