Product Description The Rosco Manufacturing Husky Series barrel offers a modern take on the Heavy Barrel (HBAR) profile, engineered for AR-15 platforms that demand superior heat management and consistent accuracy. Chambered in 5.56 NATO with a 14.50-inch length, this barrel is precision-crafted from 4150 Chrome Moly Vanadium (CMV) steel. The phosphate exterior finish is paired with a chrome-lined chamber and bore, offering outstanding corrosion resistance and ease of maintenance. While the Husky profile adds only a few ounces over the standard Bloodline 14.5 GVT barrel, the additional mass is strategically placed to dissipate heat during sustained fire and to reduce barrel whip for tighter shot groups. Button rifling at a 1:7 twist rate delivers the signature Rosco Manufacturing precision that shooters trust. Product Highlights Modern HBAR Profile: The Husky profile is purpose-built to defeat heat buildup and reduce barrel whip without significantly increasing overall weight.
