Proof Research Carbon Fiber Barrel Blank 284 Caliber, 7mm 20" Sendero Contour 1:8" Twist 5 Groove

Proof Research Carbon Fiber Bolt Blank .284 Winchester Non-Threaded Rifle Barrel 20 inch Sendero 1-8 Twist Black. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. Proof Research patented manufacturing process begins with full-profile match-grade 416R stainless steel barrel blanks that are made in the 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 developed by the advanced composites division PROOF Research ACD. The carbon fibers Proof Research uses 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 (thickness) of the barrel greatly increasing heat transport resulting in barrels that cool faster maintain accuracy over longer sessions of fire and live longer. The end result is an aerospace-grade 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. Theyre not just lightertheyre better.
