If it didn't have a pistol grip, the flash suppressor thing doesn't apply. The CT AW definition starts off with, "Any semi-automatic rifle capable of accepting detachable magazines and and any TWO OR MORE of the following features..."
So, strike one is detachable magazines. You get one other "evil feature". Flash suppressor OR threaded barrel with flash suppressor can be one as long as there's no pistol grip. That's what gets the AKs and ARs.
