Step 1: meet with your lawyer and set up a gun trust (either title 1 or title 2 NFA)
2: put all of your firearms on a schedule A or B within the trust.
3: When doc or any agent of the state ask if you own guns, legally and ethically you can say, "My wife and I do not personally own firearms". ( because the property is a separate trust asset)
Interesting. I found this link.
