Might depend on the state. IIRC, in NC you can do a "trust" for your NFA weapons and anyone on the trust can inherit the weapon with no extra fees. If it is registered to your person, you would have to get the NFA paperwork and pay the taxes before taking ownership. If neither you could probably get an NFA dealer to move it for you. I don't think the Gov is going to come after it. I don't do the NFA thing so someone may correct me. But I have looked into it a bit, just a bit too rich for my blood right now.
