Here is a picture of a mini-14 with a 40 round magazine. I got it from Perfect Union. The reason I did that is, because I got to wondering if anybody here thinks that such large capacity magazines are necessary? I have one 30 round aftermarket mag and a number of after market and Ruger factory 20 round mags. I really believe that the 20 round mag will serve for my uses. Although I do have a number of 30 rounders for my AK47.
