Looks like Amend2 is getting into the AICS short action mag game- and with some good pricing. 12 round mags for just over $20... I wouldn't think they will be replacing the metal mags for function and dependability but they should be as good as the other polymer ones that cost almost double.
I've heard that their 30 round 5.56 ones work good except in extreme heat, but no experience on that.
