Built for the AR-15 platform, this barrel is chambered in the 6mm Advanced Rifle Cartridge (6 ARC), a versatile round engineered for outstanding long-range ballistics, energy retention, and terminal performance. The PXT (PROOF eXtended Technology) carbon fiber wrapped construction drastically reduces overall barrel weight compared to traditional steel barrels while maintaining superior rigidity and heat dissipation for consistent, repeatable accuracy. With a 16\" barrel length and a 1:7.5 twist rate, this barrel is optimized to stabilize a wide range of 6mm ARC projectiles, making it an outstanding choice for competition shooters, hunters, and precision rifle builders seeking a high-performance, lightweight AR-15 upgrade.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6mm ARC Chambering:\u003c\/strong\u003e Delivers superior long-range ballistics and energy retention, outperforming traditional AR-15 cartridges at extended distances.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePXT Carbon Fiber Wrapped Construction:\u003c\/strong\u003e PROOF RESEARCH's proprietary carbon fiber wrapping reduces barrel weight significantly while improving stiffness and thermal stability for enhanced shot-to-shot consistency.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:7.5 Twist Rate:\u003c\/strong\u003e Engineered to stabilize a broad spectrum of 6mm ARC projectiles, from lighter varmint loads to heavier long-range match-grade bullets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e16\" Barrel Length:\u003c\/strong\u003e Strikes an ideal balance between muzzle velocity, rifle maneuverability, and build versatility for a wide range of applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAR-15 \/ PR15 Platform Compatible:\u003c\/strong\u003e Designed to integrate seamlessly with standard AR-15 lower receivers, providing a premium performance upgrade for serious rifle builders.\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\u003eModel:\u003c\/strong\u003e PR15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 152249\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068152249\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 6mm ARC (Advanced Rifle Cartridge)\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\u003eConstruction:\u003c\/strong\u003e PXT (Carbon Fiber Wrapped)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15 (PR15)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.315 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length:\u003c\/strong\u003e 25.1\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width:\u003c\/strong\u003e 3.8\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height:\u003c\/strong\u003e 3.1\"\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.
