Since i was repremanded from attending nfa day for having a form4 in progress I will have a few ?'s for you guys i was planning on learning at nfa day which is ...anyways... Can i buy a full auto trigger group for an M16 and put it it any lower reciever? Is it the trigger group that is registered or the lower? I have seen trigger groups at the gun show with serial numbers on them.
