I have never seen any advantage to getting an NFA trust, unless you can't get your Chief LEO to sign. In that one case it is indispensable. I do not live in WI and there can be local problems involved that I know nothing about. An NFA trust can present successor problems in some cases and some of them are just plain no good at all. Several people have had their NFA items declared contraband because of a poorly written NFA trust. I have been through the NFA process four times now and I have a current trust that I could have probably used for all four, but since my local Sheriff will sign for me on anything, I just did it the old fashioned way. The paperwork is not that bad, your dealer will do that for you and I don't think that you save any time with the trust. If you go to "subguns.com" and go to the NFA discussion forum there, you can find several discussions on this subject.Most of those guys really know their stuff.
