Yes the 80% receivers are what they are going after.You must serialized any home built firearms then you must register it with the State.....
Are they considering an 80% as "home built"?
How bout the guy that made an AK receiver out of a shovel?
Zip guns? 12 ga pipe guns?
pointy sticks?
So if you already built some without markings this is an expos facto law. Therefore unconstitutional and unenforceable.
State must submit photo of your mother.
