You saying its so does not make it so. Show me the case? Show me the law. So I guess selling the box or the rings is illegal because they are "hazardous." I have to call BS on you. Also the law is about selling. I can give them away. So you buy the box I give you a set of jarts free. Personally I think selling parts is better. Also Tell me where the line in the law is. A plastic flight is illegal? A screw that holds the tube to the rod? The aluminum tube? The plastic tube? Or is it like the an firearm the head is the considered the firearm?
