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 to stabilize a wide range of 9mm bullet weights. Its light profile barrel measures just .675 at the thinnest cross section trimming weight from the front of the gun without sacrificing the strength needed for reliable cycling. An 11-degree target crown protects the rifling at the muzzle and helps preserve accuracy by giving the bullet a clean even exit. The integrated feed ramp is machined directly into the barrel to smooth feeding from AR-9 magazines reducing the chance of malfunctions during rapid fire. Inside and out the barrel wears a Black QPQ salt bath nitride finish that resists corrosion and wear while standing up to the heat and friction of repeated firing. At 13.8 oz it is light enough to keep a pistol caliber build fast handling and maneuverable. The AR15 barrel extension is cut to milspec dimensions so it drops into any standard AR15 upper receiver without modification and the barrel is engineered to work with both Colt and Glock style AR-9 builds for broad compatibility. Whether completing a home build or upgrading an existing 9mm AR this barrel gives builders a dependable well-finished foundation for sale at GrabAGun.
