I did purchased 6 promags. I have not had any touble with them. I still wanted steel mags, so I purchased one galill mag from CDNN. I found that the bolt would miss the round on the right side of the mag. I read on another post to take some metal of the lip of the mag so the bullet would sit higher. I used my dremal and shaved the lip down. I took my saiga to the range and fired around 100 rds though the mag and had no FTF. I guess I will be buying some more galill mags. For $19.99 thats not too bad, and yes, I do have a bullet guide.
