We just got our sample magazine well (bought on the forum marketplace) made by Tac-47.. Nice looking piece, looks simple enough to attach.
Our Vepr-12 mag is a close fit. looks like two or three changes to that design. We will have a full steel locking surface, so no chipping.
Tell us if you want them. And how many.
Looking at about $58 each for an 8 round, same basic design as the saiga 12 mags we currently make.
Time line is about 4-5 months out.
