The Rival Arms RA20G103E Precision V1 Drop-In Barrel for Glock 17 Gen5 in 9mm Luger delivers match-grade accuracy with a seamless drop-in installation, featuring a 4.49" length, 1:10 twist and 6-groove rifling that maximize precision and consistency in every shot. CNC-machined from durable 416R stainless steel billet, this barrel offers superior corrosion resistance and long-lasting durability, while the low-temperature vacuum Gold PVD coating provides an exceptionally tough wear barrier to keep the finish pristine in demanding environments. A target crowned muzzle helps deliver clean, uniform muzzle performance, and each unit is individually hand inspected to ensure accuracy and reliability out of the box, with no gunsmith needed for installation. The result is a high-performance upgrade that enhances shot-to-shot consistency, extends barrel life, and maintains a sleek, corrosion-resistant profile under tough field conditions. Ideal for serious shooters who demand precision in competition or duty applications, the RA20G103E combines trusted Rival Arms engineering with practical, user-friendly use for Glock 17 Gen5 platforms, backed by a limited lifetime warranty for lasting confidence in every outing.
