The Lead & Steel L&S LS9MM16-36 AR9 9mm 16" Straight Profile barrel is built around a 16-inch straight-profile design for the AR-9 platform, offering consistent performance with a clean, uniform contour. Turned from durable 4150 chrome moly vanadium steel and finished in a QPQ black nitride coating, it is engineered for longevity and smooth shooting in a dedicated 9mm Luger setup.

This barrel’s 1:10" twist rate is optimized for common 9mm bullet weights, making it well suited for range use, training, and recreational shooting with an AR-9 carbine. The threaded muzzle with a 1/2"x36 pattern allows easy installation of compatible muzzle devices or suppressor mounts, giving shooters flexibility in how they configure their build. Lead & Steel’s attention to material selection and finishing reflects a focus on practical reliability and thoughtful craftsmanship.
