Just shy of 6 months since the ATF cashed my check, so I called today to check the status of my application. The guy was very friendly and professional, but told me that an "error letter" had been sent out to me this morning. I filled out the Form 4 provided to me by my FFL, which was on two pages, instead of the front and back of a single sheet. I learned today that they prefer a single sheet, front and back.![]()
