The K9 12.5 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.
