Just submitted my first ever NFA application, eform 1 SBR. "Pending Research" due to it being a .300BLK but the drop down for my rifle only had 5.56 so had to click off the "create new item" option. I'm very excited!
You can always just roll 5.56, it doesn't really matter what caliber you put down. Congrats on your first eForm 1!
