Product Description

Bloodline 7.5″ 9mm Barrel: This Rosco 7.5″ 9mm Barrel was designed for Personal Defense Weapon (PDW) builds where the end user might run suppressed occasionally and have the need for extended accuracy at distance out of a compact platform. 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 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.
