K9 11.5″ Kinetic Consulting 5.56 NATO
From: $185.00
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.
NOTE: COMES WITH PATROL LENGTH GAS TUBE

Ray St John (verified owner) –
Smooth, accurate, and fantastic balance, all things I expect from Rosco. My build has a Holosun laser, surefire vampire, and a Sandman S with e-brake. It balances just ahead of the magwell. Shooting it today yielded 2.5moa with cheap 55gr loads and 0.75-1moa with some Gold Dot. Followup shots were too easy and the recoil was negligible when paired with an H1 Super 42 buffer. The K9 barrels have been flawless in my testing and this 11.5 continues the trend!
