The Rival Arms RA20G512A is a 4.02" 9mm conversion barrel built to transform your Glock 23 Gen3 or Gen4 into a precision 9mm shooter. If you're looking to get more trigger time on a tighter budget or want a dedicated 9mm configuration without buying another pistol, a quality conversion barrel is the move—and this one is machined from 416R stainless steel with the fit and finish to prove it. The barrel is a straightforward drop-in; no gunsmith required.
What sets this barrel apart is the attention to detail. It's CNC-machined from a 416R stainless steel billet, which means superior corrosion resistance and durability you can count on whether you're running drills at the range or carrying in tough conditions. The black PVD coating provides a hard, wear-resistant finish that handles daily use and the abuse that comes with high-round-count practice. Inside, the BORSLICK boron nitride treatment resists carbon and heat buildup—real benefits when you're shooting fast or pushing volume through the gun.
The barrel is threaded 1/2-28, so it plays nicely with standard suppressors, compensators, and other muzzle devices if you want to add them down the road. Fluting keeps weight down while adding visual appeal. Each barrel is hand-inspected for accuracy, and the target crown is machined to protect accuracy at the muzzle. With a 1:10 twist rate and 6-groove rifling, you've got a platform built for reliable, consistent performance.
