RCM under GST

Amendend Circular Specifies supplier as  Any person, other than a body corporate who supplies the service to a body corporate and  does not issue an invoice charging central tax at the rate of 6 percent to the service recipient

Here supplier can be any person not only a registered person as specified by the circular, hence RCM will be applicable even Supplier is unregistered, 

Kindly note: Clarification with respect to the same is still awaited.
