I'm saying the specific mags I bought were defective and confirmed defective by a staff member from Marstar (he indicated he tested them himself on another gun and confirmed it - not sure if it was a Norinco or not) - and a tribute to their level customer serves - they agreed to repair the defective ones or send me me new mags they tested as not defective.
Whether all the mags in the last batch are defective - I cannot say - the 5 I bought were.
Can't comment on extra mags from Marstar but my Norc Commander works perfectly with the one it came with. It also works perfectly with the many stainlees Colt mags I have for my Colt. Its one of the new, nicely blued ones and its extremly accurate.
