storing a short barreled upper on a stripped lower?
Is it legal to buy a stripped lower and store a short barreld upper on it prior to submitting paperwork?
I intend to build a SBR over the next year or so and with some of the deals going on I would love to purchase the upper after only the stripped lower. It is my understanding that a stripped lower is undefined as to weather it is pistol or rifle. Do I first need to complete it as a pistol before putting the upper on it? I only ask because many of the parts I would be putting on the lower such as trigger, stock, ect are costly and honestly not really subject to some of the supply/deals that uppers are and I would not have any problem waiting untill I have paid and recieved the tax stamp to complete it. Of course if I do have to have the lower actually completed in pistol form to hold a short barreled upper it would be a wast of parts considering I would be making it back into a rifle as soon as I got around to doing/fulfilling the SBR paperwork.
BTW while I am new to SBR I do understand most of the paperwork involved as I have already legally bought suppressors(though for whatever reason the engraving part is still a bit intimidating).
Also as a side not I do have a complete rifle at the house for now and do not have any other stocks/buffer tube/lower parts that are not attached to that rifle with the exception of the factory m4ish stock that I would gladly give away if having it in the house was an issue. Also the rifle is mostly sold and will hopefully be leaving the house soon(as in when I recieve the last payment).
