Pretty easy to do, A) have a irrevocable trust set up, Find a really friendly lawyer could get above $200.00, B) then buy the pistol, then fill out paperwork add a check for 200.00, C) Send it (the paper work and check made out to BATFE (Do not forget the E at the end, they get snarky when you do.) off to the BATFE and sit back and wait about 6 months (if they are really trying to get the backlog caught up). Then when they send it to your LGS you can pop over and pick it up. There is a rumour, and I stress rumour, that the folks in whotterville, are seriously thinking of bagging that sys and simply doing instant checks and sending them out with in a week or so, I will believe that when I see it. Supposedly by the end of this year (2012).
And since we are on the subject of our very dear friends you can buy a full auto, but NOT take it home. (Unless you happen to have a Class 3 FFL.) It has to stay in the shop and you have to go there to use it? The other parts about the trust and stamp still apply.
