I Did this exact same thing for 4 now approved SBR’s. A DB Alloy, FGC-9, Yippee Ki Yay mp5 and The Stavka 90. The process is actually way easier then I ever imagined

This is the same one I used and all of mine got approved yesterday.

Edit… I actually used the entirety of the card and filled all the boxes with the correct fingerprint. So if you’re referring to only using the bottom section then I can not confirm that part. Sorry I responded before realizing it was referring to the bottom boxes.

Can confirm this method is acceptable. I’ve had 4 approvals listing this method for markings. Follow depth and height requirments.

Yes, and I didn’t think about that but i bet that’s the issue. They could’ve easily made a non integral unit as well

I found it just exploring the index

I realise their requirements, I’m more curious as to way they didn’t press forward on corrections and finish the BETA
