The ATF states that if you build a gun for your own use and NOT for sale or distribution, it is perfectly legal and the gun does not require a serial number as serial numbers are required by manufacturers with an FFL and an agreement with the federal government since we (most of us) are not fils and have no such agreement our self made guns require no serial.
ok, great, so here is my question, how does this work in NYS? There is NOTHING in the new law or Ny old law that says I can not build my own gun. Nothing about serial numbers in NYS. BUT if I do legally build one, how can. Register it with no serial number? In California where all guns are registered you can build a gun and not register and be totally legal.
same goes for 80% ak receiver flats.
