Body armor and plate carriers are nothing new but the demand for them has never been higher. Citizens of all walks of life are turning to body armor as a measure of preparedness in these troubled times. To meet the needs of our fellow citizens and our high standards for an armor carrier, we’ve resolved to create and supply our own.
This is the T.REX ARMS AC1.

It comes preassembled, ready to roll right out of the box as a slick plate carrier, complete with front and rear plate bags, padded shoulder straps, two buckles for attaching a placard, and an elastic cummerbund with small, medium, and large pockets.

If you are running Hesco L210s you will want the Medium AC1.

To carry additional equipment or front-loaded magazines, you’ll need to purchase a shingle, chassis, or mag pouch and attach it to either the buckles or velcro on the front plate bag. The AC1 is compatible with most of the popular mag pouches on the market.

Watch the AC1 Setup video below for information on how it is made, how to properly adjust it to fit you, and setup recommendations.
Sizing for plate carriers is based on the size of your plates. Consult the sizing chart below and watch the Setup Video above.

All cummerbunds are the same length and height (4 inches), regardless of the size of the AC1.

Because plate sizes vary, there are slight differences in the total available length of cummerbund adjustment. This will cover the vast majority of individuals. If you’re worried about being too small or too large to wear a plate carrier, measure your torso circumference (the solar plexus is a good location from which to measure) and consider the following data:

Small AC1 will fit a torso of 30″ (min) to 56″ (max).
Medium AC1 will fit a torso of 32″ to 58″.
Large AC1 will fit a torso of 34″ to 60″.

Each cummerbund has three sizes of pockets per side:
Small pocket: 2.5″, Medium pocket: 3″, Large pocket: 4″.
