The Rosco Manufacturing Bloodline 9mm Luger 5" Threaded Black Melonite Stainless Steel Barrel for Glock 17 Gen5 is a drop-in, match-grade upgrade built to tighten groups and smooth out performance on your factory pistol. Machined from 416R stainless steel and finished in a sleek black Melonite, this threaded 5" barrel is designed to deliver consistent accuracy while standing up to hard use.

This replacement barrel is ideal for shooters who want to add a suppressor or muzzle device thanks to its 1/2"x28 thread pattern. Strategic beveled edges around the chamber help reduce premature wear often seen on basic aftermarket barrels, making it well suited for range sessions, training, and competition-focused setups. Rosco’s attention to detail, from broaching and honing to final polishing and meloniting, reflects the brand’s reputation for dependable craftsmanship and thoughtful design.
