Rosco K9 16″ 5.56 NATO Nitride Barrel

Description

The Rosco Manufacturing K9 16″ barrel is an AR-15 fit engineered for consistent performance in a range of modern configurations. It features an intermediate-length gas system with an optimized gas port to run reliably suppressed or unsuppressed. The continuous taper profile is designed to dissipate heat during extended use while shifting weight rearward for improved balance with forward-mounted accessories. An updated target crown carried over from the Purebred series refines harmonics, fit, and finish.
