"...there is not registration requirement for guns in Nevada...

Ummm...excuse me? Yeah, there is. And you have to have a class 1 license or be a registered dealer to even have a full automatic weapon in your safe.

Where did you get this obviously wrong info?

Please read my full post. You missed the whole point, which was to correct the notion that guns generally must be “registered”.

And if this was an illegal Mexican Police full auto, it was not eligible for registration.
