Dude, the Etool carrier is awesome GP pouch, I've been using them this way forever. The NOD insert fits in there with an empty space in the bottom for batteries and stuff. Nalgene bottles fit perfect, you can get a poncho or lighter wet weather top in them, and like you said, it can fit 4 AK mags and five AR mags. I dont want too many people knowing this stuff and driving up the price, 😉
