Silent, simple, and you don't have to have an instruction manual to figure out how to install it on your weapon or use effectively in combat.
Uncle Sam has been issuing these basic slings for many years and we managed to get our hands on a few of them. It's getting hard these days to find a standard issue sling for your assault rifle at an affordable price.
Each "silent sling" measures 1.25 inches wide by 73 inches long and is constructed of heavy duty nylon. Two subdued, black, steel slides allow for quick assembly and adjustment for carry and tactical shooting positions. Difficult to improve on a battlefield tested sling like this. Limited quantities.
