Rosco Manufacturing K9 AR-15 5.56 NATO 13.95" Stainless Steel Barrel - Nitride - Mid-Length

The Rosco Manufacturing K9 barrel is a premium 13.95" continuous-taper replacement barrel designed for the AR-15 platform. Chambered in 5.56 NATO, this barrel is machined from stainless steel and finished in black Nitride for enhanced corrosion resistance and extended service life.

The K9 features Rosco's signature continuous taper profile with no 90-degree shouldering cuts, which shifts barrel mass rearward for improved handling balance and aids in heat dissipation during sustained fire. A mid-length gas system with an optimized gas port allows the K9 to run reliably both suppressed and unsuppressed, giving builders a versatile setup straight out of the box.

Additional features include a 1:7 twist rate for stabilizing a wide range of bullet weights, and a 1/2x28 threaded muzzle for compatibility with the vast majority of flash hiders, muzzle brakes, and suppressors on the market today.

With its rearward-shifted weight balance, optimized mid-length gas, and durable stainless steel and Nitride construction, the K9 13.95" delivers refined handling and consistent reliability across a wide range of AR-15 builds.
