Proof Research Barrel Sig Sauer Cross Rifle Pre-Fit 6.5 Creedmoor 18" 1 in 8" Twist 5-Groove 5/8"-24 Thread Carbon Fiber

Carbon fiber has long been hailed across many industries-aerospace, cycling, alternative energy-as a wonder material making everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. The 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 developed by their advanced composites division Mfg: Proof Research
