The Rosco Manufacturing HSK-115-SOC-556-7-C-CL Husky 5.56 NATO 11.50" Chrome Lined Phosphate 4150 CMV Barrel is a purpose-built AR-15 barrel that blends a SOCOM-inspired heavy profile with practical handling. Constructed from durable 4150 CMV steel and finished in a phosphate coating with a chrome lined chamber and bore, it is designed to manage heat and maintain accuracy during extended strings of fire.

This 11.5-inch carbine-length barrel features a 1:7 twist rate optimized for modern 5.56 NATO loads, with button rifling that reflects Rosco’s focus on consistent, repeatable performance. The Husky profile helps reduce barrel whip while remaining only slightly heavier than Rosco’s Bloodline barrels, making it well suited for range use, training, and general-purpose AR builds where reliability and control are priorities. Backed by Rosco Manufacturing’s reputation for thoughtful design and solid craftsmanship, this barrel offers a refined foundation for your next short-barreled or pistol configuration.
