The Rosco Husky 14.5-inch 5.56 NATO barrel (brand part no. HSK-145-SOC-556-7-MCL) is Rosco’s take on a modern HBAR from Rosco Manufacturing. The Husky profile is only a few ounces heavier than the Bloodline 14.5 GVT barrel, but it helps defeat heat and reduce barrel whip. It is made from 4150 CMV steel with a phosphate coating and a chrome-lined chamber and bore, and it is button rifled with a 1:7 twist. The barrel weighs 31.9 ounces, uses a mid-length gas system, and carries a 1/2×28 muzzle thread with an 11-degree crown. It is a durable barrel for an accurate carbine build.
