I was thinking of taking a AR pistol upper in trade for a scope, not because I have any interest in a pistol AR, just because the deal would be in my favor financially. I don't own any AR pistol lowers, but own several rifle lowers. Is it legal to own the upper without a pistol lower without a tax stamp? Technically, it would take me about 10 seconds to slap a rifle lower on it and have a SBR. Not that i'm going to but I'm not sure of the legal status here. From how I read the NFA law I should be ok as long as I don't assemble it correct? I'll eventually sell or trade the pistol upper, just wanted to be clear on it legal-wise.
