Rosco K9 11.5″ 5.56 Barrel PATROL Length Gas System (Comes w/ Gas Tube)

The K9 11.5 barrel features a proprietary patrol-length gas system for smoother operation than carbine length and greater reliability than mid-length, with an optimized gas port for suppressed or unsuppressed use. Its continuous taper design efficiently dissipates heat from hard use, and the weight shift to the rear balances the rifle perfectly with modern attachments. The updated target crown, borrowed from the Purebred series, enhances harmonics, fit, and finish. Ideal with a minimum handguard length of 10 inches.
