Blue Line Solutions JRC9G3-TB/BL 9mm 17" Threaded Barrel

The Blue Line Solutions JRC9G3-TB/BL 9mm 17" Threaded Barrel is purpose-built for law enforcement and tactical operators who demand precision and modularity in their duty or competition platform. This replacement barrel serves shooters upgrading existing firearms or building custom 9mm configurations who require suppressor compatibility and match-grade accuracy. The 17-inch length balances velocity optimization with practical handling, making it ideal for duty carbines, precision pistol builds, and operators transitioning between suppressored and unsuppressed configurations in the field.

The threaded barrel design features a 1/2x28 thread pitch—the industry standard for 9mm suppressors and muzzle devices—allowing seamless integration with commercially available sound suppressors and compensators. The 17-inch profile maximizes dwell time for reliable cycling across a broad spectrum of 9mm ammunition loads, from subsonic suppressed rounds to standard pressure factory ammunition. Precision machining and heat-treated steel construction ensure durability and consistent shot groupings, critical for tactical applications where reliability and accuracy directly impact mission outcomes and officer safety.

Law enforcement armorers, tactical riflemen, and competitive shooters benefit most from this barrel upgrade when standardizing platforms for team deployment or optimizing individual firearms for suppressed duty use. Installation requires basic gunsmithing knowledge or professional installation by a qualified armorer to ensure proper headspace and barrel lock-up. The barrel's weight of 9.7 pounds contributes to recoil management and muzzle stability, particularly valuable when mounting sound suppressors or extended-range optics for precision shooting applications.
