I have one MTK-83 Made in Belarus Weaver-style side mounts. It came with the Romanian PSL/FPK/Romak3 (or whatever they're called), but I don't need it since I got a POSP scope with integral mount. For more information, please read Tantal's website
(search for MTK-83).
Asking price: $30 SHIPPED.
Note: There are some reports that these *may* be loose on Bulgarian AKs. I can't take responsibility if the mount won't work for your application.
