The Rival Arms RA20G104E Precision V1 Drop-In Barrel for 9mm Luger delivers match-grade accuracy in a 4.49" configuration with a gold PVD finish and 416R stainless steel construction, designed to thread into Glock 17 Gen5 pistols for a seamless, drop-in upgrade. It features a 1:10 twist with 6 grooves and a CNC-machined billet profile that enhances durability and corrosion resistance, while the low-temperature vacuum PVD coating provides a rugged wear barrier for demanding environments. The target crowned muzzle improves consistency across shots, and the drop-in design means no gunsmith is required while still delivering precision that competitive shooters and serious sport enthusiasts rely on. Each barrel is individually inspected for accuracy and backed by a limited lifetime warranty, underscoring Rival Arms commitment to reliability and performance. With its combination of high-grade 416R stainless steel, precise rifling, and a durable gold finish, this barrel is an ideal upgrade for enhanced velocity, improved recoil management, and superior long-term durability in a compact, purpose-built platform.
