Here is a pic of a single point that I made. This is my first attempt at a single point and I really did not want to spend lots of money on something that I did not know would work for me. It sill needs a little work and I need to get some of the HK hooks from DSG Arms to complete it. FWIW, I think I like it, but I'm not sure it will replace my Spectre Gear SOP sling.
The sling is made from 1" tubular webbing and has two bungie sections secured inside the webbing.
