Twist rates have also been taken into account in order to optimize performance for a multitude of rounds that you may also be running out of your duty/ concealed carry pistol, in order to allow a "cross-platform" ballistic familiarity. ALL NFA RULES APPLY! Our Rosco 9mm barrels are perfect for sub-caliber carbine platforms. We have taken the time to understand the purpose of these platforms and design a barrel that will support them 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.
