Kaw Valley Precision Barrel Features The Kaw Valley Precision Barrel is machined from 4150 CMV steel and button rifled with a 1:10 twist rate for consistent accurate 9mm performance. Its light profile measures just 0.675 inches at the thinnest cross-section keeping weight down on the front end of an AR-9 build. A black QPQ salt bath nitride finish treats both the bore and the exterior surface improving corrosion resistance and making cleaning easier after extended range sessions. The threaded muzzle and 11-degree target crown round out a barrel built for both function and accuracy. This barrel features an AR15-pattern barrel extension so it drops into any mil-spec AR15 upper receiver without modification. The integrated feed ramp is designed to work with both Colt and Glock style AR-9 builds giving builders flexibility in magazine selection. At 16.2 ounces it keeps the completed upper balanced and maneuverable for range use or home defense configurations. The Kaw Valley Precision Barrel is available for sale at GrabAGun for AR-9 builders looking for a dependable nitride-finished 9mm barrel.
