From the manufacturer
The K9 11.5" and 12.5" barrels offer 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 13.95" Barrel features a mid-length gas tube, with the rest of the barrel specs remaining the same as the 11.5" and 12.5" barrels. 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 h Mfg: Rosco Manufacturing
