The Rival Arms RA20G104D Precision V1 Drop-In Barrel is a match-grade, thread-equipped 9mm Luger barrel designed to drop into Glock 17 Gen5 pistols, delivering enhanced accuracy and reliable performance for serious shooters. Crafted from 416R stainless steel and CNC-machined to precise tolerances, this 4.49" barrel features a 1:10 twist with 6 grooves and a target crowned muzzle, providing consistent projectile stabilization and clean, precise shot placement. The low-temperature vacuum PVD coating forms a durable barrier against wear and corrosion, sustaining finish integrity in demanding environments, while the stainless billet construction contributes to longevity and corrosion resistance. Each unit is individually hand inspected for accuracy, and the no-gunsmith installation promises a seamless upgrade that preserves the pistols reliability and performance. With a threaded configuration, this barrel accommodates suppressor-ready or versatile shooting setups, and Rival Arms backs it with a limited lifetime warranty for added confidence. Ideal for practitioners seeking improved precision, faster follow-up shots, and consistent groupings in competition or duty-use scenarios, the RA20G104D combines quality materials, meticulous craftsmanship, and practical compatibility in a clean, professional package.
