I went through this in October and I couldn't do more than 1 firearm/suppressor for each eFile. Can you tell me how you did it? I'm very curious.
I meant to quote your post and confirm what you were saying.
You are correct. One item at a time. Enter the information for a single SBR, pay $200. Rinse and repeat for each SBR/NFA item. The 2nd line of my post kind of hints at that, but I guess it would have been clearer had I actually quoted your post.
