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 REVERSE 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.
