The last time LS was at Drum, Riflemen could shoot full-auto outdoors. Indoors was semi-auto only, unless you where shooting from inside to outside.
As a side-note: I always think that it is cool when players go to side-arms when building clearing. Lower velocity (on average), smaller mag capacity and most being semi-auto only make them more friendly indoors and less likely to tear people up at close range. I hope that one day is becomes standard practice or a rule.
