Nope, it's a federal law that prohibits you from possessing a short-barreled shotgun or a full-auto anything. This is since the National Firearms Act of 1934. Selling such a shotgun (after being goaded into it and entrapped by a ATF agent) was what precipitated the Ruby Ridge massacre.
In fact -- and you'd think this would fall foul of the 1st Amendment -- it's illegal to distribute a pamphlet that tells someone how to convert their rifle to full auto.
