T.REX Quad Flap Chest Rig


Video | What’s Included | Magazine Fitment | Specs | Pictures | Related Info

Designed for civilians, the T.REX Quad Flap Chest Rig is an adaptable overt-style rig based on early 2000s designs with modernized features and materials. Its purpose is to accommodate the diverse and unpredictable scenarios civilians may find themselves in. It features four flapped magazine pouches, three columns of MOLLE on either side, two radio pouches, and an admin pouch to fit into whatever role you need it to.

The mag pouches are designed around 5.56 PMAGS but will fit a variety of other magazines such as AK47/74, SR25, AICS, and many more. The radio pouches are adjustable for height and fully padded for added comfort. They were designed with civilian radios in mind but will fit military radios if needed.

The T.REX H-Harness is a one-piece design that is height-adjustable by repositioning QASM buckles. Built into the H-Harness are plenty of cable management options, including two elastic loops, two webbing loops, and a generous length of sewn-in One-Wrap. Also included with the rig is the T.REX Back Strap, which provides quick adjustments and flexibility for long-term comfort. A third loop sewn into the rig itself allows the backstrap to be raised towards the middle of the rig. We find this configuration to be beneficial for certain body types and heavier loads.
