The Thorax Triple Rifle Mag Placard (TRMP) is a collaboration between Haley Strategic and Onward Research (Garand Thumb) with direct testing and feedback from the SOCOM community. The TRMP was designed as a lightweight chassis for use as a streamlined magazine placard on the Thorax Plate Carrier or as a standalone TRMP Chest Rig (TRMP-CRX) when outfitted with a harness and backpad.
