You can use Gadsden Dynamics’ Custom Chest Rig Builder to create a chest rig in any configuration you want. That means you can create a rig to carry just about anything you want… not just magazines. Gadsden Dynamics shared a pic of one creative customer’s chest rig designed to carry their tools.
You can build what you want, to do what you want. Check out the Custom Chest Rig Builder at Gadsden Dynamics.
