Featuring a 24-inch Sendero contour and a 1:8.40\" twist rate with 5 grooves, this barrel blank is crafted from 416R stainless steel and wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. The result is a barrel that is up to 64% lighter than traditional steel barrels of the same contour, without sacrificing the match-grade accuracy and longevity that serious precision shooters require. Designed for bolt-action rifle builds, this blank delivers improved heat dissipation for cooler, longer-lasting performance even during high-volume fire sessions.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSignificant Weight Reduction:\u003c\/strong\u003e Up to 64% lighter than traditional steel barrels of a similar contour, making it ideal for field and hunting applications where reduced carry weight matters.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Carbon Fiber Wrap:\u003c\/strong\u003e Wrapped with high-strength carbon fiber impregnated with a proprietary matrix resin for unmatched durability and structural rigidity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperior Heat Dissipation:\u003c\/strong\u003e Improved thermal management keeps the barrel cooler during sustained fire, extending barrel life and maintaining consistent accuracy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMatch-Grade Precision:\u003c\/strong\u003e 5-groove rifling with a 1:8.40\" twist rate optimized for 284 caliber projectiles, delivering exceptional downrange accuracy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSendero Contour Design:\u003c\/strong\u003e 24-inch barrel length with Sendero contour provides an ideal balance between weight, stiffness, and long-range performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e PROOF RESEARCH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 100943\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068100943\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 284 Cal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 24\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContour:\u003c\/strong\u003e Sendero\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:8.40\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves:\u003c\/strong\u003e 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Type:\u003c\/strong\u003e Blank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type:\u003c\/strong\u003e Rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 416R Stainless Steel \/ Carbon Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Carbon Fiber Wrapped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirearm Fit:\u003c\/strong\u003e Bolt Action Rifle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.06 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
