This 18-inch barrel is engineered for precision rifle platforms that accept Proof's Cross prefit system, combining a hand-lapped stainless steel core with an aerospace-grade carbon fiber exterior for superior rigidity and heat dissipation without the weight penalty of traditional steel barrels.\u003c\/p\u003e\u003cp\u003eDesigned for shooters building or upgrading bolt-action rifles, this barrel features Proof's proprietary layup process that bonds carbon fiber directly to the steel liner under high heat and pressure. The result is a barrel that maintains consistent point of impact as it heats, resists barrel whip, and cools faster than conventional contours. Chambered in 6mm Creedmoor, this barrel is ideal for precision shooting, competition, and hunting applications where flat trajectory and reduced recoil matter. The prefit design simplifies installation on compatible actions with proper headspacing tools.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Prefit rifle barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChambering:\u003c\/strong\u003e 6mm Creedmoor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Carbon fiber-wrapped stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Actions:\u003c\/strong\u003e Proof Cross prefit system (verify action compatibility before purchase)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Precision shooting, competition, hunting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Proof Research","offers":[{"title":"Default Title","offer_id":48449696104703,"sku":"PR134559","price":1149.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/crossa20e_169e9d39-43ed-46dc-a06e-f3b8d2f41749.jpg?v=1777264524","url":"https:\/\/doublestackstore.com\/products\/prefit-barrel-cross-6cr-18","provider":"Double Stack Store","version":"1.0","type":"link"}
