No, I do not have a will that deals with my firearms collection. I was thinking in the future I would set it up so my collection (both title i and title ii) of guns would be donated to the NRA or the National Firearms Museum. They could then use them or sell them as they need to raise capital for whatever they need.
Do not worry, I do not own any irreplaceable transferable MG's. I wish I did though! I only own suppressors and SBRs. So nothing to worry about.
However, I was thinking about having them pile all my NFA toys into my coffin with me! Well, and maybe my prized Colt Python too. I will taken them all with me. LOL
