The Wildboar Pro rifle sling is multi-functional. You can use it as an ordinary rifle sling, or, by undoing the buttons, split it into dual straps. This lets you carry your rifle on your back, like a rucsac, for travelling over longer distances, or if you need your hands free for some other activity. The underside of the sling has a non-slip surface, to stop it sliding off your shoulder, and the sling itself is made from an ultra-durable nylon and polyester blend.
