Description
The Kaw Valley Precision 9mm Pistol Barrel is a precision-machined replacement barrel for 9mm Luger AR-15 pistol builds. Cut from 4150 steel and treated with a protective QPQ (melonite) finish, this barrel is built for the wear and corrosion resistance that high-round-count pistol-caliber carbines see in regular use.
At 4.5 inches, this barrel is sized for compact 9mm AR pistol platforms, threading at 1/2×36 for use with common 9mm muzzle devices. The uniform black QPQ finish delivers a clean, low-glare appearance that pairs naturally with other black anodized and nitrided components.
Whether you are completing a new pistol build, replacing a worn barrel, or upgrading an existing 9mm pistol-caliber carbine, this Kaw Valley Precision barrel offers a purpose-built solution in a proven, durable package.
