Chambered in 6.5 Creedmoor with a 20\" length and a 1:8\" twist rate featuring 5-groove rifling, this barrel delivers match-grade precision without ever leaving your home. The pre-fit, self-headspacing design means installation requires no gunsmith and no specialized tools. Built from a 416R stainless steel core turned down to a slender profile and then wrapped in aerospace-grade carbon fiber impregnated with a proprietary matrix resin, this barrel is up to 64% lighter than a traditional steel barrel of similar contour. Enhanced heat dissipation and reduced harmonic barrel vibration ensure consistent, long-session accuracy, while the 5\/8\"-24 TPI threaded muzzle accommodates your preferred muzzle device.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrue Drop-In Fit for SIG Sauer Cross:\u003c\/strong\u003e Pre-fit and guaranteed to headspace right out of the box, enabling a complete barrel swap at home with zero gunsmithing required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Carbon Fiber Wrapped Construction:\u003c\/strong\u003e A 416R stainless steel core wrapped in high-strength carbon fiber with a proprietary matrix resin delivers up to 64% less weight than comparable traditional steel barrels.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMatch-Grade 6.5 Creedmoor Accuracy:\u003c\/strong\u003e Five-groove rifling with a 1:8\" twist rate is optimized for the 6.5 Creedmoor cartridge, providing exceptional long-range precision.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperior Thermal Management:\u003c\/strong\u003e Carbon fiber wrap improves heat dissipation and reduces harmonic vibration, maintaining accuracy over extended firing sessions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Muzzle Ready:\u003c\/strong\u003e A 5\/8\"-24 TPI threaded muzzle offers broad compatibility with suppressors, muzzle brakes, and other muzzle devices.\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\u003eCaliber:\u003c\/strong\u003e 6.5 Creedmoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 20\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:8\" (5 Groove)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threads:\u003c\/strong\u003e 5\/8\"-24 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 416R Stainless Steel Wrapped in Aerospace-Grade Carbon Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2 lbs 10 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e SIG Sauer Cross\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Drop-In, No Gunsmith Required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 134528\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068134528\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.
