I can tell looking at your rest that it is one of the older versions, i had a similar experience with my first ripcord. Only I had mine setup up to drop down on the shelf. What your hearing is the rest coming to stop against the built in stopper and there is no way to muffle that sound.
Set up the rest and nock point the way it is supposed to be and then use moleskin or the new Simms dropaway pads or a combination. When you set it up properly the rest will hit the shelf before it hits the internal stopper, and you will experience less noise.
Dropaways are going to have more noise than the WB, but it is a tradeoff.
Thanks nvshooter. I think you are probably right. The sound does seem to be something internal, and I guess I wasn't expecting it. Hopefully Ripcord has improved that in their newer models. I guess after owning it and trying it on my bow, I'm not a fan of the design. The concept seems good, but can be drastically improved upon. First, I would dampen the internal sound that mine is apparently making and second, I would make it so that it doesn't have to slap the riser shelf at all. I'm probably going to return it and try another brand of drop away, but I appreciate the help. I may start another thread to see if anyone has dropaways that aren't making contact with the shelf.
