Shit, if you were in WA and it was a legitimate transfer, I've got a couple I'd consider letting go. I'm sure any stamp collector will have some like that, you just need to find one I guess, and ideally in state.
But in that case you'll be getting what they wanna get rid of, you'll get it at a discount, yeah, but due to the circumstances the seller doesn't have to take as big of a hit either (which is why NFA stuff not including MG's is usually a one and done deal).
Didn't say how old you are, but if I were you, I'd be stocking up on nice rifles, mags, etc., liquidating bullshit, and then fill up a trust when you turn 21. I wish I had someone to give me that advice 20 something years ago.
If/when you get a trust, and they're definitely worth it, make sure you get one from an NFA attorney (rather, an attorney that does trusts and wills and also understands NFA).
