Built on a full-profile, match-grade 416R stainless steel blank produced in Proof's own firearms division, this 16\" rifle-length barrel is turned down to a significantly reduced contour and then wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by PROOF Research ACD. The result is a composite barrel that is stronger, lighter, and as accurate as the finest precision steel barrel available. Carbon fiber's unique ability to diffuse and transport heat through the barrel wall greatly enhances heat management, extending barrel life even under sustained fire. With a 5\/8-24 muzzle thread, .750\" gas journal diameter, and optimized for use with a Grendel Type II bolt, this barrel is an exceptional choice for any serious AR-platform build or upgrade.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFull-profile, match-grade 416R stainless steel core wrapped in aerospace-grade carbon fiber for outstanding accuracy and durability\u003c\/li\u003e\n  \u003cli\u003eUp to 64% weight reduction compared to standard steel barrels, coming in at just 1 lb 12 oz\u003c\/li\u003e\n  \u003cli\u003eProprietary PROOF Research ACD matrix resin provides superior composite strength and resilience in demanding environments\u003c\/li\u003e\n  \u003cli\u003eRifle-length gas system with .750\" gas journal and 5\/8-24 muzzle threading for seamless AR-platform compatibility\u003c\/li\u003e\n  \u003cli\u003e1:7.5 twist rate optimized for 6mm ARC with Grendel Type II bolt compatibility for reliable cycling\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 6mm ARC (6 ARC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16\"\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 Length:\u003c\/strong\u003e Rifle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Journal Diameter:\u003c\/strong\u003e .750\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size:\u003c\/strong\u003e .096\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 5\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Carbon Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 416R Stainless Steel with Aerospace-Grade Carbon Fiber Wrap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 lb 12 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Compatibility:\u003c\/strong\u003e Grendel Type II\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068128657\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 128657\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.
