Built around a full-profile, match-grade 416R stainless steel core, this 18-inch barrel is turned down to a significantly reduced profile to shed weight, then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by PROOF Research ACD. The carbon fiber composite construction reduces weight by up to 64% compared to traditional steel barrels while uniquely diffusing and transporting heat through the barrel wall for cooler, longer-lasting performance. With a rifle-length gas system, a .750-inch gas journal diameter, and 5\/8x24 muzzle threading, this barrel delivers match-grade accuracy and unprecedented durability for the most demanding AR-platform applications.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eUp to 64% lighter than traditional steel barrels, thanks to aerospace-grade carbon fiber composite over a 416R stainless steel core\u003c\/li\u003e\n  \u003cli\u003eMatch-grade accuracy with a 1:7.5 twist rate purpose-built for the 6mm ARC cartridge\u003c\/li\u003e\n  \u003cli\u003eSuperior heat dissipation technology minimizes point-of-impact shift during sustained, high-volume fire\u003c\/li\u003e\n  \u003cli\u003eRifle-length gas system with .750-inch gas journal diameter and 5\/8x24 muzzle threading for broad AR-platform compatibility\u003c\/li\u003e\n  \u003cli\u003eReduced harmonic barrel vibration and unprecedented durability for performance in the harshest environments\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 128671\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068128671\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber \/ Cartridge:\u003c\/strong\u003e 6mm ARC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Rifle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Journal Diameter:\u003c\/strong\u003e .750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threads:\u003c\/strong\u003e 5\/8x24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Material:\u003c\/strong\u003e 416R Stainless Steel with Aerospace-Grade Carbon Fiber Wrap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Carbon Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Contour:\u003c\/strong\u003e Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.14 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\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.
