Introducing the all new Carbon Fiber Boomstick. Featuring a unique and proprietary stainless steel insert with a carbon fiber outer sleeve, the Carbon Fiber Boomstick brings barrel technology to a new level. The stainless steel insert is built from gun drilled surgical grade 303 stainless steel and aircraft grade carbon fiber. The inside bore is honed to a 6 micron surface finish, giving you the smoothest and straightest barrel surface on the market. Carbon fiber provides a high strength-to-weight ratio, and the density of carbon fiber is considerably less than that of stainless steel. Combined with DYEs trademark muzzle break design, the all new Carbon Fiber Boomstick is quiet, aesthetically appealing and will once again set the standard of high performance in the barrel market. The surface the paintball travels on is actually micro honed surgical grade 303 stainless steel, wrapped in carbon fiber. It allows us to hone the surface so perfectly, it is comparable to 1/3 of a human hair. The Carbon Fiber Boomstick barrel provides you with longterm accuracy and consistency.
