"So, this chest rig is FANTASTIC! Your magazines will be easily accessible. Everything is right there, and very easy to get to in a time of need. The only problem with it, (very minor) is that your back is completely exposed when you're wearing it. It really isn't a big deal, but it looks very awkward, so I would advise you get some kind of backpack or hydration carrier to cover up your back a bit (only if it bugs you). BUY THIS! Especially if you're on a budget like me. Yes, it also does fit M4/M16 magazines as well as the AK mags. The other pouches are very good for things such as bb's, speed reloaders, or walkie talkies. overall, this is an amazing purchase. You definetly get your bang for your buck."
