Deadlywind Fibur-X8 W/ (1) XL Freak Insert (8") - .689 .687 .684 - All Threads - 14" 15" 16"
The Fibur-X8 barrel system consists of three parts- The thread adapter to match your gun type, a carbon fiber "main-barrel" which is the main part of the barrel (sets the length), and a FreakXL insert which sets the bore of the barrel.
The Fibur-X8 is 2x to 4x lighter than other replaceable insert barrels. And it it is strong enough to be driven over with a car (Yes, we have done it-- And we do not suggest you try it on purpose!)
Unlike other carbon fiber barrels, the Fibur-X8 barrel is built with a unique 3 layer construction. 2x2 satin Twill external, uni-direction fibers laid up in a strong multi-vector pattern, and then a super slick "Silkfiber" inside that can be safely swabbed. CNC align-bored segment for the insert area, CNC-ported with 3 rows of straight ports, and then hand-assembled and quality checked-- You can't get any more accurate.
