The Kaw Valley Precision 9mm Barrel (Kaw Valley part no. KVP9MMBBL4) is a compact 4.5-inch barrel chambered in 9mm, finished in black, built for AR-9/AR-15-pattern pistol-caliber builds. Its short length is aimed squarely at pistol-configured (braced, no shoulder stock) builds where overall compactness matters more than barrel length, whether that’s a home-defense PDW-style build or a truck gun.

Frequently Asked Questions
Does this bare barrel come with an upper or lower? No — this listing is the barrel only; you’ll need a compatible AR-9 upper and a pistol-configured lower (arm brace or no stock) to build a complete pistol.
Are there legal restrictions on this barrel length? At 4.5 inches, this barrel is well under the 16-inch federal minimum for a rifle-configured (shouldered/stocked) firearm. It’s intended for a pistol-configured AR-9 build — installing a sub-16-inch barrel on an already-assembled, shouldered rifle lower without a prior approved ATF Form 1 creates an illegal, unregistered short-barreled rifle (SBR). Always confirm your lower’s configuration before assembly.
