What states can you own a machine gun?
Can you provide me with a clear and concise overview of the states in the United States where it is legally permissible to own a machine gun? Are there any specific regulations or licenses that must be obtained in order to possess such a weapon? Additionally, are there any restrictions on the types of machine guns that can be owned, or are there any federal laws that supersede state regulations in this matter? I'm interested in understanding the full scope of the legal landscape surrounding machine gun ownership in the US.
