Fits inside range bag and backpacks. You can now carry a day's worth of ammo INSIDE your bag. Meaning you only need to carry ONE bag to the range. No more loose boxes of ammo. No more ammo cans back and forth to the range. The Ammo Transport Bag gives you the ability to carry enough ammunition and magazines to train seriously. But does not weigh you down with un-needed amounts of either. Light enough to move easily. Serious enough to have you covered for a day of training.
