I have what might sound like a dumb question about AR mags. I have traditionally bought Pmags but have heard a lot of people mention USGI mags which are said to be very reliable. What exactly constitutes a USGI mag? When I get the CDNN email they have c products mags which are metal. Some are Asian MFG (I assume Korean). So what does one look for to get a good metal AR-15 30 round mag?
