This Musket sling is made of 7/8 oz. natural, or black leather with our solid brass 1 1/4" sling buckle, that is a mid 18th century reproduction buckle. The sling is 1 1/4" wide and will vary in length, If you would like the length a certain size, just let us know and we will do our best to accommodate your request. The slings measure about 36" long which can be adjusted out another 5" longer. The slings are made to fit the Brown Bess musket, Charleville musket and we also use them on our French Fusils. The slings are adjustable by sliding the buckle to the position that you want. We have shown a photo of the sling on my french fusil to show how the ends attach to to sling swivels. On this sling both ends tie on each sling top and bottom.
