Once you click the picture you can peruse the library. This is the only sling I've made like this one so far. Most are more typical along with lanyards and ecaller lanyards
Sandstorm Slings (I believe in San Marcos) offers them. Zac is the owner and is easy to work with. He has a website. 830-730-0111. I have purhased a single point from his as well as one for a hunting rifle.
