Chambered in 223 Wylde, this barrel bridges the gap between .223 Remington and 5.56 NATO, accepting both cartridge types while providing enhanced accuracy over a standard 5.56 chamber. At 14.5 inches with a 1:7 twist rate, it is ideally suited for short-barreled rifle (SBR) configurations or builds using a pinned and welded muzzle device. The PXT designation represents PROOF RESEARCH's proprietary carbon fiber wrapping technology, which dramatically reduces barrel weight without sacrificing the rigidity, heat dissipation, or accuracy that demanding shooters require. Whether for professional use or precision sport shooting, this barrel reflects PROOF RESEARCH's commitment to uncompromising quality and innovation.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e223 Wylde Chamber:\u003c\/strong\u003e Accepts both .223 Remington and 5.56 NATO ammunition while delivering tighter accuracy than a standard 5.56 NATO chamber.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbon Fiber PXT Construction:\u003c\/strong\u003e PROOF RESEARCH's carbon fiber wrapping process reduces overall barrel weight while maintaining superior stiffness and heat management.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:7 Twist Rate:\u003c\/strong\u003e Optimized for stabilizing heavier projectiles commonly used in modern .223\/5.56 loads, supporting a wide range of bullet weights.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e14.5-Inch Length:\u003c\/strong\u003e Compact profile well suited for SBR builds or configurations with a permanently attached muzzle device to reach legal overall barrel length.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAR-15 (PR15) Platform Compatibility:\u003c\/strong\u003e Engineered specifically for AR-15 pattern rifles, ensuring straightforward fitment with standard mil-spec components.\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 PXT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber\/Chamber:\u003c\/strong\u003e 223 Wylde\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 14.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Carbon Fiber Wrapped (PXT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15 (PR15)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 152065\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 843068152065\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.
