If you take any sub-16" barreled firearm and turn it into a shoulder fired weapon without registering it as a NFA item you are committing a federal crime.
Sorry I guess I made it clear as mudd, but I was trying to say the mfg could do it either way, but not legal for us to do. And in the case of switching the T/C or Ruger around you probably never have anyone say anything about the T/C because of their known barrel options. Not sure the same would be true about Ruger, but I bet you money that if you swapped out for standard barrel and stock no one would ever notice unless in the woods and you were checked by game warden and he wanted to look at your gun.
