I was under the impression that the privilege of buying,owning,using a suppressor was granted by proper agency of us govt (ATF) after ludicrous amts of paperwork and a fairly reasonable fee. Am I mistaken in this? Do states have the right to override federal law in a way that seems arbitrary?
I never looked into it but I'm pretty sure that you could not have a suppressor in Illinois. I was an IL resident a while ago.
