Here you go, bigcountry.
An exception to that Federal $200 tax stamp on a shortbarrled shotgun. Because of a technicality in the law, this shotgun only requires a $5 stamp. From what I've heard about MD, I'm sure that most NFA (National Firearm Act of 1934) items are banned anyway, but what about A.O.W.s, (Any Other Weapons.)? You might be able to blindside them legally here, if you go for this they might have to make a new law, just for you.
No kidding, please see link, there is a waiting list on these, they are very popular. They look cool, too.
