Damn, that sucks. Sorry to hear. You could try dry lubing like I had to do with the 5.56 Korean mags I got from Cope's. I am going to try painting the follower on those with a dry lube paint and see what happens.
This kind of helped me decide what I want to do with the PDW 7.62 I plan on getting. Those mags being the only option right now really Sucks............... :
