The Lead & Steel LS9MM16-28 AR9 9mm 16" barrel is built for shooters who want dependable performance from a dedicated pistol-caliber carbine.

Its profile and length strike a balance between velocity and manageable handling, making it well suited for range use, training, and general-purpose PCC setups.
