So if I'm understanding this correctly, I can show up w/an 18" grendel upper, and my own legally registered lower. Put his DD upper on my legal registered lower, and the grendel upper on his registered lower; pay the man, and leave w/both?
It would then be up to me to form 4 for the DD lower, should I wish to return it to it's original configuration? Hmm temping....
Edit: because of the new background check laws, we'd have to do a transfer of his lower(in grendel config) at a dealer, correct???
