The Rival Arms RA-RA22G101D Essential V2 Drop-In Barrel for Glock 17 Gen3-4 delivers match-grade precision in a 4.49-inch, 9mm Luger barrel crafted from 416R stainless steel billet with a stainless finish for superior durability and corrosion resistance. The 1:10 twist with 6-groove rifling ensures consistent chambering and accuracy across a variety of match and day-to-day ammunition, while the target crowned muzzle reduces trajectory distortion for tighter groups. With a low-temperature vacuum PVD coating, this barrel forms a resilient wear barrier that stands up to harsh environments, extending bearing life and maintaining slide fitment integrity. Each barrel is individually hand inspected for accuracy and features a true drop-in design, meaning no gunsmithing is required for installation and reliable performance out of the box. Built to withstand rigorous use, the Essential V2 embodies Rival Arms commitment to precision and durability, backed by a limited lifetime warranty. Ideal for shooters seeking enhanced precision, reliability, and a durable upgrade for Glock 17 Gen3-4 platforms without compromise.
