Rosco Husky Barrel Features The Rosco Manufacturing Husky Barrel takes a modern approach to the HBAR profile delivering improved heat management and reduced barrel whip without adding significant weight over a lighter contour. Machined from chrome moly vanadium steel the 14.5 inch barrel is chambered in 5.56 NATO and cut with a 1:7 twist rate stabilizing a broad range of bullet weights from lightweight 55 grain projectiles to heavier 77 grain match loads. Button rifling is used throughout construction a process known for producing the tight consistent bore dimensions that contribute to Rosco s reputation for accuracy. A phosphate coating covers the exterior while the chamber and bore are chrome lined combining corrosion resistance with easier cleaning and extended service life. At just a few ounces heavier than Rosco s Bloodline 14.5 GVT barrel the Husky profile offers a meaningful upgrade in heat resistance for shooters running sustained strings of fire without adding excessive weight to the rifle s front end. The barrel s 1/2x28 thread pattern accepts standard muzzle devices compensators or suppressors for shooters looking to tune recoil management or add sound suppression. Weighing 31.90 ounces the barrel balances durability with a manageable addition to an AR build s overall weight. For AR-15 builders seeking a chrome lined heat-resistant barrel that holds Rosco s accuracy standard the Husky Barrel is a dependable choice.
