Rosco Manufacturing Husky AR-15 5.56 NATO 12.5" 4150 CMV Barrel - Phosphate

The Rosco Manufacturing Husky 12.5" AR-15 Barrel is a standalone AR-pattern rifle barrel chambered in 5.56x45mm NATO. Its Husky-BAR HBAR/SOCOM profile is designed to resist heat and reduce barrel whip, making this compact barrel a focused choice for an AR build that calls for a heavier SOCOM-style profile.

Rosco machines the barrel from 4150 chrome-moly-vanadium steel and uses button rifling with a 1:7 twist. The chrome-lined chamber and bore are paired with a phosphate exterior finish and a phosphate-finished barrel extension. Muzzle details include standard 1/2x28 threads and an 11-degree crown.

The barrel uses Rosco's patrol-length gas system with a 0.750" gas-block journal. A matching patrol-length gas tube is included. This New component is a barrel only, not a complete firearm or upper assembly.
