Rosco Manufacturing Husky 14.5" 5.56 NATO Phosphate/Chrome Lined 4150 CMV AR-15 Barrel HSK-145-SOC-556-7-MCL

The Rosco Manufacturing Husky 14.5" 5.56 NATO barrel with part number HSK-145-SOC-556-7-MCL is a 14.5-inch AR-15 barrel built from 4150 CMV steel and finished in a phosphate exterior with a chrome-lined chamber and bore. It uses Roscos Husky HBAR-style profile, which is slightly heavier than their comparable 14.5" government profile option while remaining manageable for general AR-15 use. The barrel is button rifled with a 1:7 twist rate, uses a mid-length gas system, and is threaded 1/2x28 at the muzzle, making it compatible with standard .750 gas blocks and common 5.56 NATO/AR-15 components.
