So I have a Haley Strategic micro 3 chest rig (D3CRM), that I wanted to use for this project, Mule Deer hunting in the back country since its light weight, already in my possession, and a product I have trained with. The Game Changer harness fit the bill perfectly in replacement of the original straps on my D3CRM rig. I had to change out the buckle clips to make it work which was no problem after ordering some from Amazon. Once installed (Very Easy) this black multicam matched perfectly, became rock solid, in fit for my body (Size Small Shirt in Under Armour), and was super comfortable the entire time. Easy and quick to take on and off for adding or subtracting layers of clothes or jackets in the back country. I would buy this Game Changer Harness 100% again and again. Thank you for making this product as a replacement part so I could build my rig for my needs Muley Freak! xxBRADxx
