I have 3 different uppers though, different barrel lengths. In the end the firearm is a restricted no matter what I do.
I have had a lower for a year and a half and I still have it registered as a lower since I always swap uppers on it.I have heard of some people picking the shortest barrel of the bunch and using that for the registration certificate, that way there's a slightly reduced chance of someone somewhere pitching a fit because your barrel is a different length than indicated on the registration card.
Mine's still a receiver only because I don't even know if the components I assembled will work. No point re-registering it until I find out if the headspace and whatnot is proper.
