Hi there, been a while since I've visited. Who can give me a for sure answer (as opposed to the "well I think maybe" answers I've found) to the question of building my own pistol from an 80% kit? If if I buy one and complete it does it need to be serialized and registered? I believe federal law says no but it seems as though Michigan law says yes, simply because it's a pistol in Michigan. Has anyone done an 80% pistol build? What did you do? Thanks.
