MCR3 MK4 – Next-generation Modular Chest Rig
The MCR3 MK4 is the fourth and most refined iteration of our popular modular chest rig, engineered to deliver maximum versatility in a compact form. Designed for professionals and enthusiasts alike, it adapts seamlessly to any operational requirement – from tactical operations and firearms training to outdoor use.
At the front of the rig, a laser-cut PALS system is integrated into a Cordura® 500D laminate, allowing for the secure attachment of additional pouches or accessories. A Velcro® panel provides space for unit patches, ID markers, or morale patches, offering both functionality and a personalized look.
Inside the chest rig, you’ll find a loop Velcro® panel and a single magazine shingle, compatible with a variety of MAGinserts. This allows for quick customization depending on your weapon platform – be it AR, AK, or PCC – ensuring optimal loadout configuration for your mission.
MAGinsert not included.
On the body-facing side, the rig features a hook Velcro® panel, covered with a removable protector flap. This makes the MCR3 MK4 fully compatible as a placard system for Plate Carriers, while also allowing it to be used independently as a standalone Chest Rig when combined with harnesses.
The top buckles are both adjustable and removable, giving you complete control over positioning and integration with your gear. Side buckles can also be detached to match different mounting setups or minimalist preferences. At the bottom of the chest rig, two drainage holes ensure quick water release and help keep the interior dry and functional in harsh environments.
The harness are not included in the set, they must be purchased separately.

Absolutely a top quality. I have the direct comparison to companies like Tasmanian Tiger, Direct Action and other top brands and i have to say mj6 is definetely in the same League!! Amazing tailoring! This chestrig is very comfortable to wear (I’ve got the H-Harness). The materials are infrared safe, what makes it really interesting for military members. All in all i can give 5 out of 5 stars.

Been using the MJ6 MCR3 in combination with the flat pocket for the last year and half and it’s still good as new! Absolutely love the molle on the sides. I put a tourniquet and a pistol mag pouch on the sides. The whole setup mostly lives on my plate carrier, but I frequently set it up as a chest rig with the EW wings and H harness attached for training purposes. The straps are nice and thin, so it’s easy to use with a backpack. Also love how small it packs when folding the wings in. Even with mags and the pocket full of stuff it makes for a small package.
Can’t recommend the enough!!
