Chambered in 5.56 NATO and machined from premium 416R stainless steel with a durable nitride finish, this barrel features Rosco's proprietary patrol-length gas system that delivers smoother cycling than carbine-length and superior reliability compared to mid-length setups. An optimized gas port ensures dependable function whether running suppressed or unsuppressed. The K9 continuous taper profile is purpose-designed to efficiently dissipate heat under sustained fire, while the rearward weight distribution pairs perfectly with modern front-end accessories for a perfectly balanced, fast-handling rifle. The updated recessed target crown, carried over from the Purebred series, delivers improved harmonics along with outstanding fit and finish. This barrel ships complete with a patrol-length gas tube and is compatible with a minimum 10-inch handguard. Manufactured in the USA.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProprietary Patrol-Length Gas System:\u003c\/strong\u003e Smoother than carbine length and more reliable than mid-length for consistent, repeatable cycling in any conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized Gas Port:\u003c\/strong\u003e Engineered to run reliably both suppressed and unsuppressed, making this barrel ideal for versatile tactical setups.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eK9 Continuous Taper Profile:\u003c\/strong\u003e The most effective barrel profile for heat dissipation during hard use, with weight shifted rearward for superior rifle balance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecessed Target Crown:\u003c\/strong\u003e Updated design carried over from the Purebred series for improved harmonics, precision fit, and excellent finish quality.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Patrol-Length Gas Tube:\u003c\/strong\u003e Ships ready to install with a matching patrol-length gas tube; compatible with a minimum 10-inch handguard.\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 Rosco Manufacturing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56 NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 12.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Material:\u003c\/strong\u003e 416R Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Profile:\u003c\/strong\u003e Continuous Taper (K9)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Finish:\u003c\/strong\u003e Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Extension Finish:\u003c\/strong\u003e Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Patrol\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Size:\u003c\/strong\u003e 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Recessed Target\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 27.05 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e AR-15 (minimum 10-inch handguard recommended)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Patrol-Length Gas Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 850039693069\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e K9-125-HY-SAGE-556-7\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.
