I just recently got some 12 round SGM mags... I bought 2 from one vendor and 2 from another. When comparing them side by side Ive noticed a few differences and havent heard anything about it in the forums. Theyre both regular Saiga mags, not any magwell version. They also look like theyre made out of different kinds of plastic. They both function properly at home but I havent shot them yet. Have you guys seen this?
In this pic you can see the different design of the front lip.
Here you can see a couple cosmetic differences in logos and wording, as well as the border/header
