I remember watching an interview with Eugene Stoner a couple years ago. He said that troops were complaining that the Viet Cong had 30 round mags while US forces only had 20 rounders. The choice was then made to issue the M16 with 30 round mags. It makes sense. Basically, most of our "enemies" use AKs, so any modern rifle meant to compete with it, should have a 30+ round mag.
