I was thinking about this yesterday and I'm still scratching my head although I think I know the answer. Before UBC's in Washington I could sell a NFA item to a private individual. They had to do the paperwork and get it approved and I could hand it over to them directly on a form 4. If I wanted to sell the guy down the street an SBR I could do that. Now I am not sure of how that works. Does the ATF NFA BG check count for the state on a form 4? How about is he wants to buy it on a trust? For a "normal" title one firearm I'd walk down to a regular FFL dealer and he'd do a 4473 and it would be a done deal. Would I need to go to a Class 3 dealer and form 4 it to him and he form 4's it out?
