ATF won't do anything about the gunsmith, neither will they come to inspect your guns. That's the most azzinine statement I've ever heard. The long and the short of it is that basically you're stuck. The case I was referring to involving the State Attorney General Office took quite a while, they were well aware of the individual who was the topic of my complaint. There had been many other complaints, eventually they filed a class action lawsuit. Several months after that my shotgun showed up unannounced, it was still in the same package I had shipped it in. Never been opened much less worked on in spite of the fact I had been lied to regarding the status of the job. When communication ceases you're in for a real hassle, sorry to be the bearer of bad news but I have BTDT.
