Rival Arms V1 4.49″ Threaded Barrel for Glock 17 Gen5, 9mm SS

Description

Your Glock 17 Gen5 is a workhorse, but the factory barrel leaves accuracy and muzzle-device options on the table. The Rival Arms V1 threaded barrel fixes both. It's a true drop-in upgrade cut from 416R stainless steel billet, so you get tighter, more repeatable groups without paying a gunsmith to fit anything. Pull your slide apart, swap the barrel, reassemble, and you're back at the range in a few minutes.

What Sets the Rival Arms V1 Barrel Apart

This one runs 6-groove rifling with a 1:10 twist and a target crowned muzzle, which is the combination that keeps your bullet stable and protects the most important part of the barrel from dings that wreck accuracy. The bore gets a BORSLICK Boron Nitride DCD treatment, a slick inner-bore coating that fights heat and carbon fouling, so cleanup after a long session is a lot less of a chore. Every barrel is hand inspected before it ships, and Rival Arms backs it with a limited lifetime warranty.

Going Suppressed or Adding a Comp

The muzzle is threaded 1/2×28, the standard pitch for 9mm cans and compensators, so it plays nice with the muzzle devices you probably already own or plan to buy. A color-matched thread protector comes in the box to keep those threads clean when you're running bare. The 4.49-inch length matches the Gen5 G17 spec, so slide fit, sight picture, and holster clearance all stay right where you expect them.

Finish and Durability

The low-temperature vacuum PVD finish is more than looks. It adds a hard, wear-resistant surface layer that shrugs off holster wear and the elements, and the 416R stainless underneath already brings solid corrosion resistance. This is a barrel built to get shot, carried, and cleaned for years without babying it. If you want a build-once upgrade for a range gun, competition rig, or a suppressor host, the V1 covers all three.
