Product Description The Rival Arms Precision Drop-In Barrel (RA20G202A) is a match-grade upgrade engineered for Glock 19 Gen3-4 pistols chambered in 9mm Luger. Crafted from premium 416R stainless steel and precision polished, this barrel rivals custom gunsmith work while delivering outstanding accuracy and performance straight from the package. The fluted exterior showcases a low-temperature vacuum Physical Vapor Deposition (PVD) coating in black, forming a resilient barrier against wear, corrosion, and demanding environmental conditions. Internally, the BORSLICK Boron Nitride DCD (Dynamic Compound Deposition) inner bore treatment actively resists heat and carbon buildup, keeping the barrel cleaner and operating at peak performance longer. A target-crowned muzzle further enhances shot-to-shot consistency, while the 1/2-28 threaded muzzle enables direct compatibility with suppressors, compensators, and other popular aftermarket accessories. A color-matching Rival Arms thread protector is included, and no gunsmithing is required for installation, making this a truly seamless drop-in upgrade.
