I KNOW you haven't lately since Md is not signing the BATF form 4s
anymore in virtually any county.
I have no need or interest in owning a fully auto firearm, but I have a
buddy out in Redneck, Virginia (but he's not a redneck) who got one made
in the Vietnam War era a couple of years ago. I asked him about the
paperwork and he said it was nothing special, and the federal charge was
something like $100 (to the best of my memory). Therefore, I concluded
it was *not difficult* to get a permit for a fully automatic firearm.
