Would a fixed magizine go around the 2 "evil features" allowing you to have a telescoping stock etc because theres no more detachable mag same with a ar pistol if you were to have a non detachable mag do those other options still apply like no more than 50oz cant have a "barrel shroud" reason I'd go with a fixed mag cause MA loaders and bf-10 loaders make basically stripper clips that'll load your mag from the side ejection port
