I only got what I think I might build. Got one for my daughter too. Bought the lowers now just in case and I don't have enough cash to build right now. Chances are that the AWB if re-instituted, is much like the first but restricts more rifles. No rifles can be built or transferred after that date. The uppers and etc. are just parts and can be made anytime and would be considered replacement parts also. IMHO
