ATF eForm 1 and ATF Form 1 applications when making your own NFA firearm will show the manufacturer as FORM 1 REGISTRATION UNITED STATES "FMI" in Box 4 of the approved tax stamp. But will you also use FMI as the manufacturer on the ATF 5320.20? No you won't. You will use the information that is located in 3b of your tax stamp application in that case.
