Ruling came down last week. It sort of surprised me that a liberal state like Minnesotta would have such a pro-2nd amendment ruling from its highest court. Anyhow... things could change there because Minnesotta never passed a law concerning "Ghost Guns". The case arose because some guy got pulled over by a State Trooper, and found an unserialized gun and was charged for having an illegal gun.
BTW: What is a Ghost Gun??? Is it spooky?

Minnesota Supreme Court rules that 'ghost guns' are not required to have serial numbers
The ruling also references that Minnesota has not regulated ghost guns on a state level yet.
