The Stern Defense AR-15 9mm Luger Barrel is a dedicated pistol-caliber barrel built for shooters running a 9mm AR-15 pistol-caliber carbine (PCC) setup. Machined from 4150 chrome-moly steel and finished in black Melonite for enhanced surface hardness and corrosion resistance, this 16.1-inch stripped barrel is chambered in 9mm Luger and features a 1:10 rifling twist optimized for common 9mm bullet weights.

Threaded 1/2x36, the standard spec for 9mm AR-15 barrel extensions, this barrel installs as a direct-fit replacement for standard AR-15 platforms. Stern Defense manufactures this barrel in the USA at a weight of approximately 1.92 lbs. Whether you are assembling a dedicated 9mm PCC from the ground up or replacing a worn barrel on an existing upper, this stripped barrel offers the durability and dimensional consistency needed for reliable feeding and accuracy with 9mm Luger ammunition.
