Proof Research PR15 .223 Wylde Carbon Fiber Rifle Barrels are changing the industry because they are much lighter more durable and more accurate than conventional barrels. Proof Research manufactures these AR15 Barrels starting with full profile match-grade 416R stainless steel barrel blanks that are turned down to reduce their weight. The prepared barrels are then wrapped with a proprietary aerospace-grade carbon fiber to provide high strength and greater stiffness for these Proof Research PR15 Carbon Fiber .223 Wylde Rifle Barrels. When you upgrade your platform with a Proof Research PR15 .223 Wylde Carbon Fiber Barrel the result will be more accuracy and more fun.
