Re: NFA transfers
No. If a gun crosses state lines, in the transfer, it must go through an FFL. If you're both in Tennessee, you can sell it to him directly (unless Tennessee won't allow it). If you're in Tennessee and he is in another state, it's got to go through an FFL, just as if it were a normal rifle/pistol/shotgun.
