What route did you go for the nfa trust? The guy in Florida?
It surely makes transfer and possession easier. I bought a safe when I bought my MAC11 just so I wouldn't risk running afoul of the law. Wish I still had that lil safe, was a used jeweler's safe, about 2 cubic feet and over 500lbs.
Now that I have a family, nfa toys have fallen off my radar. But if/when I establish a proper trust, I'll be back. Doubt I'll ever be able to play with machine guns again, but id love to have a few suppressors. Mostly shoot subsonic 22 to keep the noise down. Would love to shoot my mild 45 and 38 loads in the back yard more regularly. I can legally shoot whatever I want, but I prefer to stay on good terms with my neighbors though they're more than a stone's throw away.
