To you your sling is more than just a strap to carry your rifle or shotgun. It is an important shooting accessory that needs to be quickly adjustable in the field to use as a hasty sling to make you a more accurate shooter or to extend the length to strap it across your back to free up both hands to drag your trophy or carry gear. This is the sling you want. This is our slider buckle sling. Just grab the slider buckle with one hand and slide it to adjust it to the desired length. Tension on the buckle holds it firmly in place. This sling model has black buffalo leather and silver color hardware. Black color high quality genuine buffalo leather. Adjusts from about 26 inches to about 40 inches. 1.25-inch-wide leather strap.

Handmade one at a time in my shop in Detroit, Michigan. Each sling is cut and the holes are punched using hand tools. The edges are beveled and burnished by hand. The leather surface is finished with a formula containing natural oils and beeswax. Check out our Amazon store to see all of our products. A note about our sling swivels: The nut is free spinning, which means that when the nut is tightened to close it, the nut will spin freely until positively engaged. In other words, the nut is not supposed to tighten down. That is an intentional product design to help prevent accidental opening.
