Deadlywind Fibur-X Carbon Fiber Autocker Threaded Paintball Barrels - Fits: Ego, Geo, Dye, Axe, Mini, G6R - 8", 10", 12", 14" and 16" The Deadlywind Fibur-X carbon fiber barrels are ultra-lightweight, accurate, and quiet. They utilize the Freak(tm) 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-X has you covered! The Fibur-X 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 Freak insert which sets the bore of the barrel. Weighing in at an average 64 grams (77 grams with insert), the Fibur-X 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-X 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.
