forgive my massive amount of confusion, honestly, but i am looking up at the list and it says flash suppressor is one, but if it has a brake that would not be an evil. so the only evil would be the pistol grip, given it has no bayonet lug, suppressor, collapsible stock, and unfortunately, a 203 or grenade launcher. I guess my main confusion lies with this...If there is a brake and not a flash suppressor, and it is welded on, not pinned i should be ok with a pistol grip? given none of the others qualify.
