The ATB (Ammo Transport Bag). Most shooters prefer to only transport the ammo they need for a given day of training. And most shooters like to consolidate their mags with that ammo for the sake of convenience. Other solutions on the market did not allow for enough ammo to be carried and did not allow for mags to be consolidated along with it. Traditional ammo cans are too big to be put in a range bag. Molded plastic solutions are not flexible enough and existing options were too too small. So we developed the ATB to overcome those issues and give you as much range convenience as possible. Because we are shooters too. And we know this was needed.
