What is the quick release rifle carrying system used by Randy Newberg? I have looked and asked other places but cannot uncover who makes it or what it is called?

The Kifaru works for some but I hated that extra 8lbs directly on my hip. I did get used to the barrel directly in the peripheral but after several trips I could not get completely comfortable with the weight directly on my side hip.
