"Well, let me say that this chest rig doesn't hold six mags,it holds up to TWELVE mags, plus room for about two mags on the side. The mag pouches have removable and adjustable Velcro straps inside if you want to have an open top for easy access to your mags. M4 mags fit perfectly, AK mags CAN fit in the pouches, but they stick out. Theres plenty of MOLLE webbing for extra accessories. Adjustable straps for easy fit. In the inside, it has small pouches closed with velcro for anything you have that can fit. Pretty great chest rig,very durable, 1000D. Would recommend"
