silent, I have the same thing on the string of that bow as I have on all of my bows. A tied in nockset with an eliminator button, and a fletcher superpeep. This bow is not a freak, I have set up several four runners for guys that perform every bit as well once you take into account the different draw lengths, and grains per lb.
