The Blackhawk Universal Swift Sling can be used with a wide variety of front sling mounts and fixed or collapsible stocks. Designed to be ambidextrous, it's fully adjustable and made of 1. 25-inch nylon webbing. Its heavy-duty hardware consists of a metal oval ring and 300 pound side-release tri-glide buckle. This buckle provides quick and easy emergency detachment. For maximum strength, the sling has robust bar tacking and box stitching. The newly integrated Quick-cam buckle provides for rapid one-hand adjustment and shoulder-to-shoulder transition. It takes the place of all prior versions of the Blackhawk Swift Slings.
