This "Ammo" pouch is much larger than I expected. I ordered it not for ammo but to attach to my back pack and put a CB radio and batteries in the front pouch. I still have extra room and my CB is "Old School" large. I've learneds from the past to not leave batteries in the CB. Also I tape the batteries together with the polarity the same to prevent corrosion. As soon as it arrived(Early) I ordered another one for my Scanner,Portable Radio,and NOAA weather radio. And there's still room for a flashlight,compass,and Cell phone. With the exception of the CB all of these items are miniature and work like a charm out in the desert. I would highly recommend this item.
