I've gotten tired of taking a bunch of cases and ammo cans when I go to the range. I came up with this design to hold my 3 uppers/2 lowers. There's room for mags, ammo, targets, eyes/ears and other range needs. And it's modular so I have a smaller case to put on top that will carry pistols and cans. The bin is a 28 inch ridgid on wheels, 3d printed some mounts as well.
