Rosco Manufacturing Husky AR-15 5.56 NATO 10.30" 4150 CMV Barrel - Chrome Lined Phosphate

The Rosco Manufacturing Husky series brings a SOCOM-inspired profile to the AR-15 platform, and this 10.30" configuration is chambered in 5.56x45mm NATO. The barrel is button-rifled from 4150 Chrome Moly Vanadium (CMV) steel - a tough, heat-resistant alloy chosen for high-round-count service.

The bore and chamber are chrome lined for extended service life and easier cleaning under sustained fire, while the exterior carries a phosphate finish for corrosion resistance and a low-glare working surface. A 1:7" twist rate stabilizes a broad range of 5.56 NATO bullet weights, and the muzzle is threaded 1/2x28 for standard AR-15 muzzle devices and suppressors.

As Rosco's take on the SOCOM 10.3" barrel, the Husky series delivers the handling and balance of a compact AR-15 build in a tough, no-nonsense package designed for hard-use platforms.
