For an AR pistol, do NOT attach a buttstock or a buffer tube that can accept a buttstock and do NOT attach a vertical forward grip.
To keep from going the pistol route, there are many people, me included that will take the upper to a friend or relative and let them hold on to it untill the paperwork comes through.
