The ESD Sling is highly customizable to any rifle sub-gun shotgun hunting rifle bolt action and PDW weapon system. There are two adjustment sections on the ESD sling. A rear adjustment section to fit the ESD sling to your body size and additional gear. And a quick-adjust section to loosen or tighten the sling while in use. The ESD Sling adjustment system is more adaptable to natural body movement and body mechanics. The 1-inch width of the ESD sling has less friction than wider slings and allows the ESD sling to move across your body without resistance. The ESD sling has an elastic regulator that prevents webbing from twisting or jamming when adjusting. This elastic has a natural pull tab that allows the sling to be folded upon itself and stored tightly on the weapon system. This feature is great for patrol vehicle storage or bag/pack/case storage. Simply pull on the ESD Sling to deploy the sling to its full length.
