The Rosco Manufacturing BL-G19-9MM-M-TB-V2 Bloodline 9mm Luger 4.62" Threaded Black Melonite Stainless Steel Barrel is a drop-in, match-grade upgrade for Glock 19 pistols from Gen 1 through Gen 5. Built from 416R stainless steel and finished in a durable black Melonite treatment, this threaded 4.62" barrel is engineered to enhance accuracy and reliability while maintaining a sleek, understated look.

This Glock 19 barrel is ideal for shooters who want a refined, duty-capable setup for range use, training, or everyday carry. The 1/2"x28 threads allow easy mounting of suppressors or other muzzle devices, while strategic beveled edges around the chamber help reduce premature wear compared to basic aftermarket options. Rosco’s attention to detail in broaching, honing, polishing, and Melonite treatment reflects the manufacturer’s reputation for consistent craftsmanship and thoughtful design.
