Another question, If i register a lower as a SBR can i buy any short barrel upper i want for it after that. I.E. can i get a 10" 9mm upper if i want? As long as it only goes on that upper.


that's why i went SBR and to keep clutter in the safe down (sure!) i'm using this QCB upper www.mgimilitary.com one upper 2(for th emoment) calibers both 10.5"
