I have several mini 14's and a AC556 I have always run factory 10 and 20 round mags and never had any issues. Was thinking might want to grab a few high cap stick mags while I can in case something stupid happens. I have a a couple beta mags but was thinking about some sticks. Anyway my first instinct was ruger 30's but they have some horrid reviews. Triple k 30 and 40's have better reviews but some say stay with the ruger 30's others say anything over a 20 in a mini is asking for a headache, any one out there have any experience with high caps in a mini or AC ?
