8" Freak XL insert version. 0.697" post-bore and quad porting.
The Deadlywind Fibur-X8 carbon fiber barrels are ultra-lightweight, accurate, and quiet. They utilize the Freak XL(tm) 8" replaceable inserts, so one barrel and a few inserts will do the job of multiple barrels. And with the ability to affordably swap to different threads, the Fibur-X8 has you covered!
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. Note- You MUST use a GoG "Freak XL" 8 inch insert with this 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 4 rows of straight ports, and then hand-assembled and quality checked-- You can't get any more accurate.
We use LEFTY threads to join the Main Barrel to the Thread Adapter- no bits getting stuck in your gun!
You must have at least a "Thread Adapter", a "Main Barrel", and a "Freak XL insert" to use this barrel system.
