Well, first of all, I can't even begin to think about affording anything full auto at the moment, but I was just curious as I thought you had to have a class 3 FFL to "own" full auto. I guess I never really looked into it. From what you are saying though, it sounds like a similar process for getting a short barrel shotgun or suppressor. Just pay the tax stamp and do the paperwork and wait.
If I ever have a spare $5000 bucks to blow on a gun it's going to be a SVD.
