magazine carriers

All of my ar focus has been accuracy and range shooting.  I got to thinking about a vest to carry several mags. I'd be laughed off the range if I showed up with one, but thought having a grab and go setup has entered my mind. I'm too fat for a belt and figured a vest would work for me. I doubt I'd ever have a need for one and if I did, I'd probably not last long enough to use many mags, but I'd still like to have one. Any ideas?
