They will put that you have 6 months to get all your guns registered, or else you are a felon. NFA has a 6 month wait currently so for registration of current firearms there would be like a 24 month wait minimum. So 6 months into your wait you are a felon, no weapons for felons. Double trouble your going to prison. Unless you turn those firearms in before the 6 month period. Prepare for the ass raping fellas.
