That’s an interesting way of spelling, “no.”
Most states do not require firearms registration. There’s a handful that explicitly prohibit it. As far as states that have a general firearms registration is concerned, it’s limited to Hawaii and DC, so sure… you’ll get some people on a list there.
CA, CT, NY - there’s only a registry for certain types, not all.
There’s also no federal firearms registry whatsoever.
So if a list is < 1% complete, that’s good enough?
