I have been using 550 paracord for anything I can for about two years now. I make everything from zipper pulls, key chains, survival bracelets, belts, and now slings. My belt that I wear everyday has approximately 125-130 feet of 550 cord. I recently made a sling for my 4595ts utilizing about 90 feet of cord. In my opinion it is a way better option than the basic sling that comes with the carbines. I am willing to make these for anyone who wants one. I would need you to send me your sling studs and the length you would like it. They can be made in any color or any two colors. I chose desert camo with a black outer layer. I tie them tight, but they are still loose enough to be very flexible and comfortable. Material costs would be about $20 and since I would be paying return shipping, I would ask for $20 for my work and shipping. Please contact me if you are interested.
