The new DYE GF Boomstick TM is the next evolution of the Legendary Dye barrel lines. Glass Fiber ‰ÛÏGF‰ barrels are constructed using the same proprietary assembly process as our tried & true Carbon Fiber ‰ÛÏCF‰ barrels but make use of our new Glass Fiber ‰ÛÏGF‰ Technology which not only allows for amazing strength and durability, but also allows for complete customization of color. This unique fusion of materials and Dye‰۪s 20 years of barrel experience have produced yet another progression in performance of our barrel line. Just like the ‰ÛÏCF Series‰ barrels, the ‰ÛÏGF Series‰ barrels feature an optimum back length of eight inches allowing the paintball to reach terminal velocity before porting begins to optimize performance. The GF/CF Boomstick TM lines are the most accurate, quiet, and efficient barrels currently available.
