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 accuracy across common 9mm bullet weights. The light profile barrel measures .740 at the thinnest cross section keeping the compact 4.5 length balanced and manageable on a short pistol build. An 11-degree target crown protects the muzzle s rifling and supports a clean even bullet exit for repeatable accuracy. The integrated feed ramp is machined into the barrel to smooth magazine feeding helping the gun cycle reliably even at speed. The barrel carries a Black QPQ salt bath nitride finish inside and out standing up to corrosion heat and repeated cycling. At 9.5 oz it keeps a short AR-9 pistol light and quick to maneuver in tight spaces. The AR15 barrel extension is cut to milspec dimensions so it drops directly into any standard AR15 upper receiver and the barrel is built to function in both Colt and Glock style AR-9 configurations. This compact barrel gives builders a dependable option for a short maneuverable 9mm pistol caliber build available for sale at GrabAGun.
