Just so there are no misunderstandings among folks who might read your post and not get the significance of what you've said.

Your picture certainly made a blip on my radar and my first thought was "he better have the approved Form 1 or Form 4 and tax stamp to go with that".

"18 U.S.C. § 921(a)(8) provides, “The term “short-barreled rifle” means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches” and Section 921(a)(6) provides, “The term “short-barreled shotgun” means a shotgun having one or more barrels less than eighteen inches in length and any weapon made from a shotgun (whether by alteration, modification or otherwise) if such a weapon as modified has an overall length of less than twenty-six inches.” Similarly, the National Firearms Act, in essence, defines it the same way in 26 U.S.C. § 5845(a), although it is broken down slightly different."

In short, it is illegal for a private citizen to possess a short barreled modern smokeless powder shotgun without proper registration and tax stamp from the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Dicking around with the semantics between 'sawed off shotgun' and 'short barreled shotgun' and suggesting there is no such thing as a 'sawed off shotgun' per the BATF could lead to a misinterpretation that could get someone in serious trouble.
