Proof Research’s patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are turned down to a significantly reduced profile, then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. The 101001 Sendero contour delivers a 24-inch barrel length with 1-10 twist rate, weighing just 3 pounds, making it an ideal choice for precision shooters who demand superior accuracy without the weight penalty of traditional steel.
The carbon fibers have a unique ability to diffuse heat along the length of the barrel and move heat very effectively through the barrel wall, resulting in barrels that cool faster, maintain accuracy over longer firing sessions, and live longer. The aerospace-grade carbon fiber offers specific strength up to 30 times that of stainless steel and specific stiffness up to 7 times greater than steel. The barrel offers up to a 64% reduction in weight compared to traditional steel barrels of similar design.
All Proof Research barrels are rifled using single-point cut rifling, lead lapped and thoroughly inspected at multiple quality control stations throughout the manufacturing process. The bolt-action barrel arrives ready for thread and chamber by your gunsmith, giving you the flexibility to build a custom rifle tailored to your exact specifications and chambering requirements.
