“Lust For Life” Custom Leather Rifle Sling Hand Tooled and Made in the USA. My tribute to Vincent Van Gogh. All of my rifle slings are custom one of a kind designs. Thus you will have an unique one of a kind rifle There is an adjustable strap which ensures a comfortable fit and the high-quality leather material ensures durability for years to come. My rifle slings work best with 1 1/4 inch rifle swivels. If your swivels are smaller you can always cut a “v” into the rifle sling to accommodate your swivel. There is at least five hours of labor in each rifle sling. I also do one of a kind leather slings based on your requests.
