This Weapon Sling was originally designed for use with the legendary M239 (SAW) light machine gun. Nylon shell over a steel cable core is very tough, not to mention heat-resistant to prevent failure near a hot barrel. And the super-sized shoulder pad is intended to deal with serious weight, since the M249 is up to 22 lbs. fully loaded.
But beyond its original use, this Weapon Sling is very customizable. The shoulder pad is completely removable if you want to cut down on bulk. And the nylon strap under the pad is adjustable to make this Sling a better fit for normal-sized rifles. On each end is a length of cable covered by webbing, and each of these cables has a carabiner clip on each side for quick disconnects. So you can take one or both cables off if you just want the nylon strap. This is a great military collectible, but also a cool starting point for lots of custom tactical solutions.
