Description
The Rosco Manufacturing K9 Sage Dynamics is a 12.5-inch barrel chambered in 5.56x45mm NATO for AR-15 platform rifles. It is built from stainless steel with a black nitride finish and a 1/2-28 thread pitch for muzzle devices.
The barrel uses a 1:7 twist rate and a continuous taper profile intended to dissipate heat during sustained use. It has an updated target crown and a patrol-length gas system, which the retailer describes as operating reliably both suppressed and unsuppressed.
The package includes a patrol-length gas tube. The barrel is listed as fitting the AR-15 platform.
