I saw some Polish Radom Beryl 5.56x45 magazines listed on Gun Broker. They look a lot like 5.45x39 mags, and pretty cool at that. They are going for $30 each. I have a SAR 3 and an Arsenal SLR 106fr. Bulgarian Circle 10 mags work for both of these rifles, but I'm not sure about the Radom mags. I know that 5.56 AK's tend to be quite particular as to which 5.56 mags they'll accept. Do any of you have any experience with the Polish Radom Beryl 5.56x45 magazines? Thanks.
