Looks like a great idea! I don't have an AK-74 so I don't need a mag like that, but I can certainly vouch for 10-round mags. The 30-round mags look cooler, but a 10-round mag is way more convenient for shooting. As a matter of fact: I rarely shoot with anything else, since the larger mags make it difficult to find a comfortable shooting position. And who can afford to load up a 30-round mag nowadays anyway?
