I live in Massachusetts. I can't get the following shipped into the state.
Ammo, of any kind, including "ammunition components" brass, bullets, primers, powder
Knifes
Lasers
Mags over 10rounds
Mind you, there is no actual law prohibiting this, but the AG threatens anyone who ships into the state with all sorts of fines/lawsuits etc. Gun Owners Action League, a MA base firearms rights group, has been fighting this for years, to no avail.
