Good day all, I was interested in buying a machine gun in oregon from a private party. I am aware that i need to do the $200 federal tax transfer with my local sheriffs dept, and that the paperwork can take a few weeks?. But what can i do to make the money exchange safe and without complications, before the m.g. owner can legally hand over the m.g.to me. ( I am assuming that the private party owner, keeps the m.g. till my background check and paperwork clears?).. is it normal/ acceptable,, to just leave a good deposit with the private party?( I just would not feel comfortable to hand someone 10,000 to 20,000 dollars and they still keep the gun till i cleared..thnxs..
