Rosco Manufacturing Bloodline 5.5″ 9mm M4 1:10 Twist Black Nitride Barrel

Bloodline 5.5″ 9mm Barrel: This Rosco 5.5″ 9mm Barrel was primarily designed for suppressed carbines/ pistols where the handguard will be run 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. 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 deliver the performance you seek from these barrels, whether you are running suppressed, defense, subsonic, or supersonic ammo (depending on barrel length). Twist rates and lengths have all been taken into account in making these barrels.
