My rifle is an Impact action in a MPA chassis, 6.5 CM. I have been using a couple Magpul magazines that I already had while I got the barrel broke in and am now ready to get some better mags. I'd like to get a couple AICS 10rnd mags. Can someone enlighten me to the differences between them AX, AW, and so on. Anything that works as good or better (in your opinion) than an AICS? THANKS!!
