The State vs Fed angle has already been tested in Kansas. Did no work out so well, but at least the State stepped up and helped defend both the manufacturer and buyer that were arrested. This helped the Judge in his decision for a light sentence.

The Kansas law was modeled after the Montana law that did make it to the supreme court.
"Kansas modeled its law on the Montana Firearms Freedom Act, which the Court of Appeals for the Ninth Circuit has found to be invalid, according to court filings.
State firearm nullification laws, or firearms freedom acts as they are sometimes called, have been signed into law in nine states. In addition to Montana and Kansas, other states with them include Alaska, Arizona, Idaho, South Dakota, Tennessee, Utah and Wyoming, according to Everytown For Gun Safety, which advocates common-sense gun control laws.
The legal maneuvering comes against the backdrop of President-elect Donald Trump's election following a campaign that made gun rights a rallying cry for his supporters. A new U.S. attorney general will also be in place at the Justice Department.
And in another twist, the man who helped write the state's gun law — Kansas Secretary of State Kris Kobach — is now a potential pick for a job in the Trump administration. Kobach has called this case "a perfect example of a prosecution that should never occur."
Sentencing is set for Feb. 6."
