I got a whole rig from a guy for my new G3. He sold it to me for $25 and some ammo. The way he has it set up it can take 14 mags. That's 280 rounds of 7.62x51 NATO. That seems kind of excessive to me but then again I'm use to bolt action rifles. Even with the shoulder straps this thing is heavy. I mean relay heavy and I'm short stocky and in shape. I'm not sure if he planed on moving much with this thing on but I don't see it happening. I was thinking more along the lines of using one of the two mag capacity pouches. So thats 40 rounds pulse another 20 in the gun.I can throw one of the 6 mag capacity pouches in my pack if it comes to it and that frees up space on the belt for my pistol, bayonet, and flashlight. I bought this so that I could have my bug out bag and battle pack as two different entities for different situations. So is there a concensius on how much ammo you should be carrying around on your belt or in your pack.
