Ear plugs! Plain and simple! Give up before you start! You will never quite a CB down like you can a vertical bow, just not going to happen. Its alot of power in a short stroke and not all that energy goes into the arrow. Sometimes I think the stock acts like a megaphone and helps to make some of the sound. Well all go through what you are about to go though and it will never be as quite as a vertical. Some guys with vertical quite them down so to maybe get a second shot, not going to happen with your CB!
