QAD Ultra Rest. It locks in the upward position and fully contains your arrow so it will never fall off the rest. It is just like the ripcord except the ripcord will fall down if you draw your bow and let down and the Ultra rest will only fall if you shoot
Awsome rest I highly recomend it!Have had one on my Outback since Feb.and has work flawlessly,quiet,and easy to set up.
