Proof Research 260 Rem Defiance Ruckus Pre-Fit Carbon Fiber Barrel

The Proof Research 260 Rem Defiance Ruckus Pre-Fit Carbon Fiber Barrel features unprecedented accuracy, performance, and relentless excellence. The carbon fiber and steel barrels for Defiance Ruckus were designed to be simple to install. The pre-fit barrels are chambered and threaded for a simple install that require only a few specialized tools. Simply torque your barrel on, double check headspace with proper gauges and head to the range.

* PROOF drop-in barrels are designed to fit Ruckus actions with the ‘Recessed’ bolt nose option only and will not be compatible with actions that have cone, flat, or control round feed bolts.

Why Carbon Fiber?

Carbon fiber has long been hailed across many industries such as aerospace, cycling, alternative energy. It is recognized as a wonder material that makes everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. The Proof Research patented manufacturing process begins with full profile, match grade 416R stainless steel barrel blanks that are made in their firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high strength, aerospace grade carbon fiber impregnated with a proprietary matrix resin. This Resin is developed by Proof Research’s advanced composites division, PROOF Research ACD.

The carbon fibers that Proof Research use have a unique ability to diffuse heat along the length of the barrel, much like fiber optics transmit light. Carbon fiber also moves heat very effectively through the wall of the barrel increasing heat transport resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and live longer. The end result is an a high fiber content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and durable to perform in the most demanding environments. They’re not just lighter, they’re better.
