The Rival Arms RA20G701E is a match-grade drop-in barrel built to bring out the best in the Glock 34 Gen3 and Gen4. Chambered in 9mm Luger and measuring 5.31 inches, it's CNC-machined from 416R stainless steel billet and fluted along the exterior, which shaves a bit of weight and helps the barrel run cooler over a long string of fire. If your G34 is your competition or range gun and you want tighter, more repeatable groups than the factory tube gives you, this is the kind of upgrade that earns its keep.
The rifling runs a 1:10 twist with six grooves, a solid all-around pitch that stabilizes the common 115 to 147 grain 9mm loads most people feed a Glock 34. The muzzle is target crowned, which protects the rifling and supports a consistent point of impact round after round. Lockup is where a good aftermarket barrel really shows itself, and Rival Arms machines these to tight tolerances so you get a snug fit with minimal wobble compared to a stock barrel.
The gold PVD coating isn't just for looks, though it does dress up a slide window nicely. It's a low-temperature vacuum finish that lays down a hard, wear-resistant barrier that holds up in rough conditions. Inside, the bore gets Rival Arms' BORSLICK Boron Nitride DCD treatment, which resists heat and cuts down on carbon fouling. That means less scrubbing at the end of a range day and easier cleanup overall.
Installation is straightforward. Pull your slide, swap the old barrel for the Rival Arms unit, and reassemble. No fitting or gunsmithing required in the vast majority of cases. As with any aftermarket barrel, it's smart to run a box or two through it to confirm reliable function with your carry or match ammo before you count on it. Made in the USA and backed by the Rival Arms warranty.
This barrel is made specifically for the Glock 34 Gen3 and Gen4. It's a true drop-in replacement, so it installs without gunsmithing in the vast majority of cases. It is not cut for Gen5 slides, so make sure your G34 is a Gen3 or Gen4 before ordering.
No, the RA20G701E is a standard non-threaded barrel with a target crowned muzzle. If you're planning to run a suppressor or comp, you'll want to look at a threaded Rival Arms barrel instead. This one is aimed at precision and competition shooting rather than muzzle devices.
In most cases, no. Rival Arms machines these to tight tolerances as a drop-in fit, so you just field strip the slide, swap the barrel, and reassemble. It's still a good idea to test fire with your intended ammo to confirm reliable function before relying on it.
The 1:10 twist and six-groove rifling handle the full spread of standard 9mm loads well, from lighter 115 grain practice ammo up through heavier 147 grain rounds. This makes it flexible for both range days and match use. Try a few different loads to see which one your particular setup groups tightest with.
