So prior to me having issues with my Saiga, I found this website and ordered some rebuild kits. He had the Promag AK-A5 - .223 mags. I picked one up at the gun show a few months earlier and it worked great without a bullet guide. I also had picked up a Promag for the Saiga that had the piece of crap plastic bullet guide which broke. (don't buy from anyone)
(I ordered a couple from him and the springs weren't the right type.. they were for a AK 7.62x39. He said no problem and was going to refund me, I contacted Promag, and Steve there sent me the replacement springs free of charge,,,,
