Damn, guys, it's just a URL.

Yes, I have that rig for my AR mags. Bit heavy with 8 mags, and tricky to get into or out of fast. I'm also a little uncomfortable with the retaining strap; it's either too tight and restricts deep breathing, or too lose and allows the rig to bounce around. I've replaced it with a plate carrier, but I haven't gotten rid of it as a backup, and have no plans to do so.
I think I paid 55 or 60 for it a few years ago, and it was hard to find back then.
I got mine in black so as to not stand out too much when wearing a blue and black camping backpack. It was an outstanding match for the backpack. Most padded rigs and nearly all vests interfere with backpack fit; this one doesn't, and even rides above the hip belt.
AK magazines are considerably larger and heavier than AR mags. I'm almost certain that two wouldn't fit in each of those pouches, and it's entirely possible that even one won't squeeze in.
ETA: Wow, duh, there's an AK version at your link. Sorry about that, they only made them in AR when I got mine. I would lay good money on their AK rig living up to its advertising about mag fit, although it would probably have the same restrictions I mention above pertaining to my AR one (and to most such chest rigs).
