No, all Saigas accept any AK mags, even drum mags. A converted saiga is one that now complies with US SEC 922R Compliance. So, its legal now!Very nice!! I used to have one which I dearly loved and foolishly sold. I was under the impression at the time that Saigas only took standard 10 round mags and that they wouldn't accept real AK mags. Is that what you meant by conversion? I wouldn't have sold mine if I knew you could get 30rd mags for it.
