[Nightcrawler]

Here is an example of the twelve magazine vest. This model is set up for holding M14 or other twenty round .308 magazines. 240 rounds of 7.62x51mm is hard to beat! It'll be heavy, though. If you're going to rely on a system like this, it'll help to be in shape. (Though, putting on the vest, plus a CamelBak full of water, and loading it with 12 fully loaded FAL magazines, and then going for a long walk three times a week will get you into shape pretty quick...)
