10.5" 1:10 Twist 9mm Barrel - Black Nitride

Build a high-performance pistol caliber carbine or truck gun with the Always Armed 10.5" 9mm Black Nitride Barrel. Proudly Made in the USA, this 10.5-inch barrel offers the ideal balance of maneuverability, velocity, and accuracy for AR-9 pistol builds and short-barreled rifles (SBRs).

Machined from premium 4150 Chrome Moly Vanadium (CMV) steel, this barrel features a Light HBAR Profile that increases rigidity and heat dissipation without adding unnecessary nose weight. The protective Black Nitride finish penetrates the metal surface to deliver extreme corrosion resistance, reduced friction, and long-lasting durability inside and outside the bore.

Chambered in standard 9x19mm Parabellum, the precision 1:10 right-hand twist rate ensures stable projectile flight and tight groupings across common target and defensive bullet weights. Threaded in the industry-standard 1/2x36 TPI pitch, it safely prevents accidental installation of standard 5.56 muzzle devices while providing seamless compatibility with 9mm flash hiders, compensators, and sound suppressors.
