Rosco Manufacturing K9 11.5" 5.56 Hybrid 1:7 Twist Black Nitride Patrol Barrel - $114.95 (Free S/H over $175)

Description

Description
The K9 11.5 offers a proprietary patrol length gas system that is smoother than carbine length, more reliable than mid-length. Features an optimized gas port to run reliably suppressed and/or unsuppressed. The K9 continuous taper is the most effective profile to dissipate heat from hard use. With weight shifted to the back of the barrel, modern attachments on the front of the rifle create a perfectly balanced and better handling rifle. Updated target crown carried over from the Purebred series with improved harmonics, fit and finish. We recommend a minimum handguard length of 10″ with this barrel.
