You have to find one to own.
You can’t own a new weapon manufactured since 1986.
Read somewhere that there are only about 175,000 registered automatic weapons in the USA.
So crap guns cost thousands. Good ones...
It’s pretty crazy. A brand new full auto M-16 was not much more than a semi except for the tax stamp. Now they are 15-25k if you can even find one.
Well, with a class II license, parts kits or machining skills, you can make you own, file the paperwork, and get the tax stamp. But then again, that would be non-transferable. The restriction on post 1986 is that they can’t be transferred.
