I'm a current resident of Oregon, soon to be moving permanently to Washington. I have a variety of NFA items. SBRs on Form 1s, Suppressors on Form 4s, some are individual, some are on a trust. I'm understanding that I'll need to complete, submit, and receive approval of a Form 5320.20 prior to permanently moving any firearms. Researching, it appears my Oregon based trust should still be valid in Washington State. Most articles discussing SBRs in WA are talking about Form 1s being denied by the ATF. Would I have a problem with a Form 1 SBR that's already been approved in OR being transferred into WA? Or is all that business over with? Are Form 1 SBRs being denied in WA still? Anything else I'm missing?
