thanks Leo; you beat me to it. I have some nerve damage in my left hand, so I had to try a different but very similar approach. I grab the ring with my right hand, but still so my thumb is close to the barrel that holds the rib in place. I then put some pressure on the ring, pushing away from my body. My left hand is holding the rib steady so it doesn't flex, and then with my right thumb I release the barrel from the ring.
I'll try your way tonight and see if that's easier for me.

Thanks PacAce! I just tried your Octo stow method and it works great!
