Rosco Bloodline Barrel | Glock 17 | 9mm | 4.49 in

The Rosco Bloodline barrel is a match-grade, drop-in replacement designed for Glock 17 pistols (generations 1–4). It is manufactured from 416R stainless steel, broached, honed, polished, and finished with a Melonite treatment for enhanced durability and corrosion resistance. This barrel is rated for use with SAAMI-approved, factory-new ammunition and is intended to improve the accuracy and performance of a stock Glock pistol. Installation is a user-friendly swap, though Rosco recommends consulting a qualified gunsmith if you have questions about fitment.

Common applications include precision target shooting and range training where consistent, repeatable performance is required.
