just got a new AK. have owned many. very much prefer 20r mags in an AK. would like to get some metal ones to go with my pmags. orignal hungarian 20s are impossible to find and way overpriced and often rode hard. KCI makes 20r metal. their rep is not so good but i read somewhere(?) that there is "gen 2" version out. also read the the 20r being shorter (?) have fewer issues than the 30s. anybody have any info on this?
