Rosco Bloodline 5.5″ 9MM Barrel
All ATF/NFA Rules Apply – See NFA tab for details
This Rosco Bloodline 5.5” 9mm barrel was primarily designed for suppressed carbines/ pistols where the handguard will be ran over the rail. It will give you the flexibility of running a suppressed platform that offers the most compact size possible without sacrificing performance. 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.
The Rosco Bloodline 5.5″ 9mm barrel is 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.
