I've been doing a bit of research on this myself.
My understanding is if you have a lower that started out as a rifle you cannot make it a pistol. However, a lower that starts out as a pistol can be converted to a rifle.
Of course if you buy a lower and build your own stuff no one is the wiser but a purchased rifle taken apart and the lower used as a pistol is a no go.
Am I wrong here?
