Actually really nice and actually purchaseable - Viking Tactics Wide Padded Sling MK2 with Cuff Assembly

The quality is top notch and if you are looking for cuff sling you have only a few options, this and the ulefdhenar PRS. This one was made in america and available in more colors than just black. Aside from the comparisons and limited options the sling is well made, well padded for heavy rifles, and is worth the money. I purchased two products previously and was disappointed. If you want to learn the fundamentals of sling shooting a cuff sling is necessary.
