While I know of a few cases where federal law can force a state to have looser restrictions (for example, the second amendment), it's pretty uncommon. Usually if a state wants to ban something, it can ban it and federal law can't stop such a ban without a pretty strong constitutional justification.
The Second Amendment isn't even really Federal law, nor is the rest of the Constitution. It's the supreme law that sits above Federal/state law and constrains what Federal/state laws can do.
(And the Tenth Amendment protects state laws significantly from Federal laws, where applicable.)
