I was having to much neck & back pain from a single point sling , plus since my brain surgery I have wires running up my neck . I like having the gun hanging down in front of me so I came up with this 
It balances perfect for me
I welded 3/16 rod to a magplul 180 sling mount- forgot to add the strap is a tactical gun holder strap that fits over my shoulder thus relieves my neck pain know I can carry my gun for hrs in relief of pain . I had to cut all the straps off & sewed longer ones on.
