From the bit of research on the forum I have been able to do, it sounds like most people recommend the CMI mags for function at somewhere like 100% of the time. It sounded to me like the general consensus on the Type 57 mags from Taiwan (the blued ones) was also good. Since I need to buy quite a few, I would like to hear opinions on the functioning of the Type 57s. Has anyone had bad experiences, or do these function as well as the CMI's? From my research the price difference is at %40 as the Type 57's are about $15, while the CMI's are about $25.
