Same problems as last time, plus a "real AOW" and an "undetectable firearm" ban for no obvious reason (except to maybe make the rest of the bill pass?). No grandfathering, and still basically bans all home gun manufacture of any kind. You could, in theory, save your current non-3D-printed stuff by taking it to a SOT to have them engrave a serial (which, ironically, the state will still know nothing about). Does seem to ban 80% kits without a serial. A clever SOT in this state could, in theory, just buy the kits, engrave serials on them, NOT RECORD THEM, and then sell the kits completely legally. Putting a serial number on it doesn't make traceable, guys. IIRC, the ATF only knows about serials because of the books, and 80%s are not in the books!
There's a lot wrong with this bill. If the state insisted they wanted to know about all home gun manufacture, they could easily have people apply for a serial from the MSP LD portal, which would infringe on everyone's freedom much less.
That could be interesting. Will have to look closer at that.
