7.5" 1:10 Twist 9mm Barrel - Stainless Steel

Build a precision pistol caliber carbine (PCC) or compact AR-9 pistol with the 7.5" 1:10 Twist 9mm Stainless Steel Barrel. Engineered for high maneuverability, quick target acquisition, and smooth cycling, this barrel provides the perfect balance of compact size and full ballistic expansion for the 9x19mm Parabellum cartridge.

Precision-machined in the USA from premium 416R stainless steel, this barrel delivers superior accuracy, thermal endurance, and exceptional corrosion resistance. The Light HBAR profile adds necessary rigidity to minimize barrel whip without adding unnecessary weight to your front end.

Featuring a versatile 1:10 twist rate, it provides rapid bullet stabilization across a wide range of grain weights—from light 115gr range ammo to heavy 147gr subsonic rounds. It comes finished with a standard 1/2x36 TPI thread pitch specifically designed for 9mm muzzle devices, helping prevent accidental mounting of .223/5.56 accessories.
