The Rosco Manufacturing BL-G17-9MM-M-TB-V2 Bloodline 9mm Luger 5" Threaded Barrel is a drop-in, match-grade upgrade for Glock 17 Gen 1–4 pistols. Built from 416R stainless steel and finished in a durable black melonite treatment, this threaded 5" barrel is engineered to enhance accuracy and reliability while remaining duty ready for hard, everyday use.

This Rosco Bloodline V2 barrel is designed to fit factory Glock 17 slides without gunsmithing, giving shooters a straightforward path to improved performance at the range or during training. The threaded muzzle allows the use of compatible muzzle devices or suppressors, while strategically beveled edges around the chamber help reduce premature wear often seen on basic aftermarket barrels. Rosco’s careful broaching, honing, and polishing process reflects the brand’s focus on consistent craftsmanship and dependable performance.
