Thanks all for your help, I watched the National Gun Trust video on how to efile a form 1 as an individual for an SBR and it was what I needed, first timer here. I have a friend who was just denied and I'am not sure if I understood him correctly or not  but he mentioned using the FMI code incorrectly. He has CZ Scorpion pistol he's gonna SBR but I'am building an AR from a stripped receiver which are two different items.  I'am listed as the maker/owner of the SBR in the ATF's eyes but I didn't manufacture the serialized part so I would not use the FMI code, I believe it's mainly used for suppressors.

Thanks!
