Ordered a complete lower from ST, which it will be shipped to my LGS. God knows when they will ship it eventhough i already paid for it. Bought a complete upper SBR and it will arrive next tuesday. Question: Can i just keep the SBR upper in a locked unused rifle case in my home. I will not touch it until the paperwork is done (till my lower arrives at my LGS, submit the paperwork with trust $ $200 tax. And another 6-7months waiting for the stamp gets back). I will not even putting accessories on my upper when its being kept. Seriously will not touch it from now till the whole 6-7months. Thank you for inputs.. appreciate it. I just want to be a law abiding gun owner .
