AK for 7.62X39--Check out Classic Arms. They usually have a good deal.

.223, go with AR. Even Ruger has come out with an AR. The Ruger 556.

Mini 14 mags are expensive. Cope's has them for 40.00. I'd rather have 3 PMags. There is a new Mini 14, tactical looking, but AR's rock. Lots of choices, can even get a 22LR conversion for it.,
