Product Description The Rosco Manufacturing Bloodline barrel is a premium drop-in, match grade upgrade engineered to enhance the accuracy and performance of any stock Glock 17 (Gen1-4) pistol. Chambered in 9mm Luger and featuring a 5-inch threaded muzzle, this barrel is purpose-built for shooters seeking a reliable and precise aftermarket option. Each Bloodline barrel is crafted from 416R stainless steel and undergoes a meticulous manufacturing process: broached, honed, and polished to exacting tolerances, then finished with a durable black Melonite coating for corrosion resistance and long-term durability. Strategic beveled edges surrounding the chamber area have been incorporated into the design to significantly reduce the premature wear commonly found on basic aftermarket barrels. The end result is a duty-capable barrel upgrade that delivers performance without compromising quality. Product Highlights Drop-In Match Grade Fit: Designed as a true drop-in replacement for Glock 17 Gen1-4 pistols, providing an immediate accuracy upgrade with no gunsmithing required. 416R Stainless Steel Construction: Made from premium 416R stainless steel for superior strength, corrosion resistance, and long service life. Black Melonite Finish: A broached, honed, and polished bore is treated with a black Melonite coating, maximizing hardness and surface protection. Strategic Beveled Chamber Edges: Beveled edges around the chamber area reduce premature wear compared to standard aftermarket barrels, extending the service life of the barrel. 5-Inch Threaded Muzzle: The 5-inch threaded barrel adds muzzle length for improved velocity and allows for the attachment of muzzle devices such as suppressors or compensators.
