I have never built a ghost gun. I buy stripped lowers, which are serialized from the factory.OMG, not a Ghost Gun!!!
Another stupid word like "Assault Rifle" that doesn't really mean anything, but sounds scary to the soy crowd.
I understand that but this kid ordered the firearms from an online dealer, so I'm guessing he bought at retail.
If I had a mill, I'd build ghost guns all damn day. If you have no plans to sell it, you can build anything you want, and have nary a mark on it. I can even build a full auto weapon, if I felt like filling out a Form 1.
