Last I read, Vermont and Alaska are the only states in the Union where you don't need a license or permit to own or carry a firearm, though exact rules probably vary.
These bills have nothing to do with concealed carry but rather, manufacture and possession of firearms and ammo within the state. It is specifically stated that firearms and ammo manufactured within that state and RETAINED within that state cannot be regulated by any Federal entity and any laws pertaining to such manufacture or sales do not apply and cannot be enforced. Those attempting to do so are violating the law of that state.
