I purchased a 10.5" upper a while ago on the EE and for a while was interchanging it with the lower on my 16" Bushmaster. I decided that I liked the 10.5 and decided to purchase a dedicated lower for it so I purchased a RRA lower off the EE as well.
When I received the certificate for the lower, it said "Frame/Receiver Only". My question is, do I need to re-register the the lower to indicate that it is now a complete rifle? My thinking is 'NO' because in a heartbeat I can change out the lower to whatever upper I want, but it just seemed strange that the CFC would say that it was a frame/receiver only.
