C products defense mags for your ar47 - Duramag 7.62x39mm Stainless Steel 5 Round Rifle Magazine

Building an ar to fire 7.62x39 with a bear creek arsenal side charging upper. These seem to be the only magazines I can find. I have not had a chance to test out the batch I've purchased but they appear to be well made. They rattle a bit more than most 556 mags, so take that into consideration. May try adding some base plates for the 20 rounders, the 10 round mags are easy enough to insert.
