The CF Boomstick™ sets the new standard for barrel performance. It is constructed using a proprietary process combining Stainless Steel and Carbon Fiber. This unique combination of materials and Dye’s nearly 20 years of barrel experience has yielded an advanced performance filled barrel. The barrel also features an optimum back length of eight inches, so the ball can reach terminal velocity before porting begins. The CF Boomstick™ is the most accurate, quiet, and efficient barrel currently available. Available in Cocker/Matrix marker threads.
