To update this post, all I can say is I REALLY tried to work this out with Silencer Shop, but I finally demanded a full refund. To their credit, they did do that, but I won't be doing any more business with them for a while. I tried over fifty times, with three different computers, at times from 2am, 5am, late evening, and mid afternoon to use their "full auto" software to send my form 1's, but it failed every single time. I emailed their tech support four times over a week and never got ANY response, I did the chat thing twice, and all they would do is refer me to their tech email. I called and waited, and waited, and waited on the customer service line, with no response. I did the leave a call back number option and five hours later I did get a human being who said the tech people would eventually email me back. I asked if I could actually speak to them and was told no. I asked if I could get an approximate date or time for a response email and I was told they didn't know. I asked if they could just send me my EFT fingerprints and I would fill out the form 1's myself and was told it was against company policy. Then the very polite, but condescending, customer service person said, "Don't worry, this will all work out." That's what I tell my wife when the shit hits the fan and I don't have a clue what to do, so I requested a refund. I then went to Printscan, got my EFT file and less than an hour later, my forms were submitted (manually by me). I get that the deadline is getting close and I'm also to blame for waiting this late, but I truly thought this brace rule would be paused by one of the courts. Seeing the battle going on in the house of representatives gave me hope that it would be. I am still convinced that eventually this rule will be ruled unconstitutional like the bumpstock ban. But since that might take several years and I don't have any assurances, I decided to cave and file the form 1's. Anyway, that's my experience for what it's worth.
