On making this an SBR, you will need a stamp, but you need a stamp if you buy an SBR, so it is a wash. These are so cheap, (got mine nib for $300, 2 30 rnd mags, ffl transfer), that you could get a top of the line folding stock, engraving and the $200 stamp for way less than you could buy an AK 47 SBR and do the $200 transfer plus other ffl fees. I may do this eventually, because that was my original intent, but it has become to versatile and useful as a pistol, that i changed my mind.
AK 47 pistol - $300
ffl transfer - 0
hours of immense pleasure and peace of mind - priceless
