Rosco Bloodline 9mm 4.49 Inch Non-Threaded Barrel

The Rosco Bloodline 9mm barrel is engineered as a drop-in replacement for Glock 17 pistols in generations 1 through 4. While installation is straightforward, Rosco Manufacturing recommends consulting a local gunsmith if you have questions about the swap. This barrel accepts SAAMI approved, factory new ammunition only. Rosco’s Bloodline line delivers match grade performance that improves accuracy and function over factory Glock barrels. Each barrel is constructed from 416R stainless steel, broached, honed, polished, and melonited for durability and precision.
