The NZ ban is why I would never register my guns. If they know you have it they can force you to give it up. They can not take what they do not know you have. Anyone who wants to put some things away should look at the P80 and the AR15 Ghost guns with a jig. You can buy these and they are not considered a gun until you finish it. Before you finish it, you can sell it our just put it away. No serial no and it can be shipped to your door even in California the peoples republic. https://www.full30.com/watch/MDE2NjM5/fastest-polymer-80-build-speed-hack

It does cost more to set up with the jigs and if you don't have the tools but in the end you have a total legal and untraceable gun or guns the gov has no idea exist. I have no doubt the pussy gen. snowflakes will one day get the constitution over turned and ban them. Put them away now cheap and deep.
