Building an SBR on an 80% lower. I called and talked to the ATF about the "manufacturer" and have that squared away. Since I am listed as the manufacturer I know that's going to get a small warning on the site. What I didn't expect is I listed the model as ar15 and it says the model is unknown. Should I assume this is due to the manufacturer? Probably should call the atf back but wanted to see if anyone else has ran into this.
Thanks
