If you do feel the need to get the SBR stamp in the future, let me know and I'll walk you through the process. It's really straightforward, there's just a whole lot of waiting (I'm going on 4 months right now) and driving around (to the Sheriff/CoP for signatures, the local Walgreens/CVS for passport style photo, and to the local police station on a day they do their public fingerprinting) involved. Local sheriff is usually the best place to go for the signature too, because most of 'em are very firearm friendly (only request the local sheriff had was that I get a gun safe before he signs off on any machineguns, and that's not entirely unreasonable).

And now that SMG isn't doing runs of them anymore, it's almost impossible to find one that's built from the ground up as an SBR (though you could always get one of their PPS43 SBRs).
