Product Description The Rosco Manufacturing Husky Series barrel is inspired by the classic SOCOM 11.5 profile, purpose-built for AR-15 platform builds that demand reliability and precision in a compact package. Machined from mil-spec 4150 Chrome Moly Vanadium (CMV) steel, this 11.5-inch barrel combines a robust Husky profile (HBAR/SOCOM) that helps dissipate heat more effectively and significantly reduces barrel whip during sustained fire. The exterior is finished in a durable phosphate coating, while the chamber and bore are chrome lined for enhanced corrosion resistance and extended service life. Button rifling with a 1-in-7 twist rate delivers the Rosco accuracy the brand is known for, making this barrel an excellent choice for SBR builds, home defense, or duty use. Product Highlights Heat Management and Reduced Barrel Whip: The Husky (HBAR/SOCOM) profile adds just a few ounces over the Bloodline 11.5 barrel while providing superior heat dissipation and stability during rapid-fire sequences. Chrome Lined Chamber and Bore: Full chrome lining on the chamber and bore greatly improves corrosion resistance and makes cleaning easier, extending the service life of the barrel. 4150 CMV Steel Construction: Machined from mil-spec 4150 Chrome Moly Vanadium steel for outstanding durability, toughness, and resistance to wear under high-pressure firing cycles. Button Rifled for Precision: Button rifling produces a consistent, smooth bore with a 1-in-7 twist rate optimized for stabilizing a wide range of 5.56 NATO projectiles. Suppressor and Muzzle Device Ready: Threaded 1/2x28 at the muzzle with an 11-degree target crown, compatible with a broad selection of muzzle devices and suppressors.
