The D3CR-H addresses the same mission as the original D3CR” but has been slightly redesigned to support .308 platforms. Optimized for work in urban” vehicle” rural and other confined settings” the Disruptive Environments Chest Rig was built to be worn as a stand alone system with a detachable X-harness or clipped into a armor platform equipped with a quick release system. When run as a stand alone” the platform is low profile enough to be worn fully loaded and not print on a normal/loose fit jacket or sweatshirt. When run on a armor platform with a quick release system” such as SwiftClips” it can be attached or stowed in seconds” giving the end user the versatility to transition from low vis to high vis or vice versa. The rig intentionally does not include a radio or dedicated full size medical pouch so no matter the posture” essentials such as communications and medical kits can remain on the end user at all times. The D3CR Heavy is also compatible with the Haley Strategic D3 Expansion System allowing the end user to add features including the holster wedge or multi-mission hanger pouch.
