Mags are stupid. Stripper clips and a fixed mag are where its at. NONE of the disadvantages of the other two systems. No mags to get damaged or lost. You can carry much more ammo without the extra weight of the mags. No fragile mag catch to malfunction. Reloads are equally as fast. Yada Yada. You get my point. There are advantages and disadvantages to BOTH systems. I prefer the AR system but I like the AK platform better for my purposes. I wouldn't see any advantage in replacing the mag setup on the AR with one from the AK or vise versa. Both systems (all three if you include the stripper clips) work fine. Remember, most of the serious wars of this world were (and many still are) fought with bolt action battle rifles. The AK and AR are both GIANT leaps in technology but they are all just fancy lead throwers. Pick your favorite and practice until you are good at it.
