The Rival Arms RA20G104A Precision V1 Drop-In Barrel for 9mm Luger delivers match-grade precision in a threaded, black PVD-coated 416R stainless steel barrel designed to fit Glock 17 Gen5 pistols, offering a simple, no-gunsmith installation that lets you elevate accuracy without downtime. Crafted from CNC-machined 416R billet, this barrel emphasizes durability and corrosion resistance, while the low-temperature vacuum PVD coating provides a robust wear barrier in demanding conditions.

Each RA20G104A is individually hand inspected for accuracy, reinforcing the brands commitment to precision manufacturing. The threaded barrel configuration combined with a precision fit enables reliable, seamless integration into Glock 17 Gen5 frames, making it a practical upgrade for competitive shooters, service members, or law enforcement enthusiasts seeking enhanced performance from a trusted, factory-ready platform. This drop-in option pairs reliability with a limited lifetime warranty, delivering long-term confidence in every shot.
