The SOC-C Releasable Vest Sling (SOC-C-RVS) was designed from the ground up to integrate with the CIRAS vest system made by Eagle Industries. The sling becomes a component of the releasable mechanism and allows the weapon to instantly and reliably release from the vest when the cut-away pillow is pulled. It also eliminates two other common problems with vest mounted sling systems; 1) It uses a strap that comes over the shoulder and connects low in the back allowing the weight of a loaded weapon to be spread out over a larger area. 2) It doesn't pull the front of the vest down and reduce your armor coverage like slings that attach on or near the shoulder strap. Included in the price of the sling is one of our female fastex adapter strap universal stock loop, long. The sling is also fully compatible with any other female adapters in our SOC-C Modular Sling System including those found in our Contractor Pak.TM NOW COMES WITH YOUR CHOICE OF ONE OF THE ADAPTERS LISTED BELOW.
