Our Rosco 9mm Barrels are perfect for sub-caliber carbine platforms. We have taken the time to understand the purpose for these platforms and design a barrel which will support it effectively. It is our goal to get you the performance that you seek out of these barrels whether you are running suppressed, defense ammo, sub-sonic ammo or supersonic ammo (depending on barrel length). Twist rates, and lengths have all been taken into account when we set out to make these barrels. Browse our high quality 9mm AR15, pistol, and SBR barrels today!
