Exactly, so, the supremacy clause would seem to have a conflict with this.I'm not sure on this, but, I don't think the supremacy clause means what you say it does.Needless to say, this idiotic ‘law’ is un-Constitutional – it clearly violates Article VI.Superfluous, but excellent.
The Arizona House passed a law to nullify federal gun control measures last last month, establishing the state as a Second Amendment sanctuary.

The supremacy of Federal laws is a fact settled, accepted, and beyond dispute; the states and local jurisdictions are subject to Federal laws and the decisions of Federal courts (see Cooper v. Aaron (1958)).
Residents of the states and state and local lawmakers will obey and comply with all Federal laws – including Federal firearm regulatory measures.
If the residents of Arizona believe a given firearm regulation violates the Second Amendment, they’re at liberty to file suit in Federal court to seek to have that law overturned.
There are constitutional powers delegated to congress in the 18 enumerated powers, and in THOSE constitutionally delegated powers, federal law is Supreme, but I don't think this act is meant to imply that federal law supercedes all state law.
If the supremacy clause overrode all other laws, then the inclusion of the 18 powers would have been pointless. It would also mean that the federal government could exert dictatorial powers over the entire nation should one party manage to wrestle power and find a way to keep it.
Thoughts?
The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.
