WTK: Squires Bingham AK-22 mags that can be converted from other mags?

[5.45]

I have a HTA converted AK-22 that is a Squires Bingham AK-22, problem is it came with NO magazines! I was told that these are the same magazines that Ciener used for his AR-15/M-16 conversion, with the sheet metal box welded on though. Anyone know what if any mags that can be converted and used in these guns? Any help would be appreciated! I am having the worst time with this.

Thanks 5.45
