This 5.5” Rosco 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. ALL NFA RULES APPY!

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.

Note: 9mm barrels are measured a bit different than 5.56 barrels.

For this barrel 5.5", to use a no piston suppressor a 4.25" Hg is recommended. HG will stop 1/8" behind thread shoulder.

For this barrel 5.5", to use a piston equipped suppressor a  4.5" can be used most of the time. HG will stop 1/8" bast thread shoulder. If using a 4.5" HG it may be best to mock up HG,barrel, receiver and can to ensure there is at least 4.5" of space between can and receiver.

For this barrel 5.5" , to use our Linear Comp a 5.5" HG is recommended.
