So, one can't put in a 16 inch barrel but keep the welded stock on? I giess it woukd feel better shooting with the full stock though....
As far as I know, you can't do that with a welded up folded stock. Overall length is too short to be considered a rifle. It has to be at least 26" overall. Someone correct me if I am wrong.
Assuming the receiver was never made into a rifle, then it's a pistol since the folding stock welded shut doesn't count as a stock.
99% of the time I keep my pistol in the pistol configuration because I like the the original SMG look.
I occasionally swap it to the rifle config. Its nice to open the stock. But then its back to pistol config with welded closed stock and its hung back up.
