I have a few slings for sale, handmade by me and the wife. The tan and green ones are 550 cord, the other colorful ones are braided cord. The ends are melted and secure, but can be unwound in case of a survival-type situation.
The first is tan and ACU green, the sling swivels are attached in the braid and included. It's 24" long overall. $18 shipped including two swivels.
And me with it on my shoulder. Rifle is a Marlin Camp 45.
The second is ACU green and OD green. It has no swivels attached, but I do have a set of black ones and a set of silver-colored aluminum I can add if requested. Shown looped through the single point plate and front swivel on an AR. 35 inches long because of the attaching loops. Asking $15 shipped, $18 if you want me to add a set of black swivels, $20 for the aluminum, what I paid for them at the shop.
