The Rosco Manufacturing HSK-145-SOC-556-7-MCL Husky 5.56 NATO 14.50" Chrome Lined Phosphate 4150 CMV Barrel is built as a modern HBAR solution for AR-15 builders who want heat management without excessive weight. Its Husky SOCOM-inspired profile, mid-length gas system, and button rifled 4150 CMV steel construction work together to maintain accuracy as the barrel heats, while the chrome lined chamber and bore enhance durability and ease of cleaning.

This 14.5" 5.56 NATO barrel with a 1:7 twist is well suited for range use, training, and mid-range shooting where consistent groups and smooth recoil are priorities. The phosphate exterior finish and .750 gas block journal make it a straightforward fit for standard AR-15 uppers and common components, whether you plan to pin and weld a muzzle device or integrate it into a compact rifle build. Rosco Manufacturing’s reputation for in-house button rifling and careful QC gives this Husky barrel a solid foundation of reliability and craftsmanship.
