Product Description
The Rosco Manufacturing Bloodline 12.5" 5.56 NATO barrel is purpose-built to bridge the gap between Short Barreled Rifle (SBR)/Pistol and Reconnaissance (RECCE) platforms, delivering outstanding precision performance in a compact package. Designed and manufactured entirely in-house by Rosco Manufacturing, this barrel is crafted from premium 4150 Chrome Moly Vanadium (CMV) steel and engineered to outperform the competition while standing up to heavy, sustained use. The Government profile and Carbine Length gas system make it the ideal foundation for the ultimate intermediate patrol platform. A Nitride finish on both the barrel and barrel extension provides superior corrosion resistance and long-term durability, while the 1/2x28 threaded muzzle ensures compatibility with a wide range of standard AR-15 muzzle devices.
