Chest rigs have a long history of use, even dating back to World War I. The tradition of individuals carrying extra munitions, tools, and supplies in chest rigs has continued to this day with both classic and modern versions widely used throughout the world. The T.REX ARMS Ready Rig is our take on what a chest rig should be for the modern-day citizen.

It is a lightweight, low-vis chest rig with elastic pockets for magazines, tools, medical, and other equipment. Designed around an elastic cummerbund combined with an adjustable X harness. It comes ready to roll right out of the box, simply adjust it to fit you (watch Setup Tutorial Video below) and you’re good to go. Affordable. Comfortable. Stable. Concealable. American made.

It holds three 5.56/STANAG magazines in the front, and then includes on each side of the rig: one small multitool cell, followed up by a STANAG-sized cell, and then a larger cell which fits our EDC ITRK perfectly, or other general-purpose items. Similar to the cummerbund on our AC1.

The Ready Rig is One Size Fits Most due to its ability to be adjusted both in the cummerbund and in the harness straps.
For measurement instructions, see below.

Watch the Ready Rig Setup Tutorial video below for information on how it is made, how to properly adjust it to fit you, and setup recommendations.
The Cummerbund (unstretched) is 44″ long at max and 29″ at minimum (negates the use of last 4″ pocket).
This will cover the vast majority of individuals. If you’re worried about being too small or too large, measure your torso circumference. The solar plexus is a good location from which to measure.

Each cummerbund has three sizes of pockets per side:
Small pocket: 2″, Medium pocket: 3″, Large pocket: 4″.

The Harness Straps have 35″ of useable material. This allows the shooter to wear it as high or as low as they’d like.
What size do I need? How do I set this up?
Watch the Setup Tutorial Video above. It answers most, if not all, questions about the Ready Rig. If you have other questions after reviewing this page and watching the setup video, email our Customer Support at [email protected]
Will this work with 7.62×51 or other DMR style mags?
They will not fit. But we are planning on a version for DMRs in the future, it will solve all of your EBR/M110/SVD/SCAR needs.
Will the 556 Ready Rig fit the great and mighty 7.62×39 magazines?
Negative. It is a VERY tight fit and is not recommended. The future 7.62 Ready Rig is what you’ll want for that.
Will the 556 Ready Rig fit 5.45 magazines?
Yep! They’re a tighter fit than a standard STANAG magazine, but work just great.
