SBR Build, school me

If I want to buy a SBR upper for my existing rifle are you allowed to use both barrels/uppers after that? Let's say a 10.5" and currently installed 16" ...or is it now a SBR period?
After the Form 1 for your lower is approved and it is classified as an SBR, you can use whatever upper on it you wish. That is my understanding. If I'm wrong, I know someone will correct me shortly.

Edit: If you are asking if you can just buy a short barreled upper and make your rifle an SBR without any other paper work, @stickflickin is correct. You have to use a pistol lower with a brace.
