State laws cannot supercede Federal laws. I would think this would be ripe for a challenge.
It's actually more complicated than that, kind of Byzantine; in SOME areas (like controlling air traffic) the Feds have taken the field and the states have no role. In other areas, authority is co-extensive, and the feds will restrict you and the states can restrict you further.

The Feds make weed illegal, so when the states say it's legal, it's still illegal. But where the Feds say (for example) that you can obtain rounds for your M-203 grenade launcher if you pay the tax, but your state outlaws all bombs, then you can't have bombs in your state.

There's another category, where Federal law explicitly says that states can't bar gay "marriage" and they can't legislate separate white & colored drinking fountains.

Bottom line, states ban all kinds of gun stuff that the Feds permit. Try and buy an AR-15 or some hollowpoints in NJ or NY.
