Best Aftermarket Glock Barrels
1. Faxon - Editor's Pick
Faxon's has impressed us with many of their AR-15 barrels, handguards, and bolt carrier groups, and their Glock barrels are no exception.
They have been accurate, and they also offer multiple coatings and configurations so you can get the look you want.
We have tried both their standard models as well as their threaded models for suppressor usage. You can see one of their threaded TiN barrels with a suppressor in action below.

2. Grey Ghost Precision - Best Bang for Your Buck
Grey Ghost Precision is another company that is well-known for its awesome aftermarket goods.
We've tested out a few of their products, including a Glock barrel, and really liked what they had to offer. Bottom line --- the barrel we tried was awesome.
Whether you want a threaded or non-threaded model or want to upgrade your slide, you can probably find what you're looking for. Grey Ghost has options for both the Glock 19, 17, and the 43 too!

3. Lone Wolf - Best Conversion Options
Lone Wolf has earned the reputation of being one of the leading manufacturers of aftermarket Glock accessories in the industry.
Do you want to completely rebuild your Glock? Yeah, they can help with that.
While it should come as no surprise that Lone Wolf makes their own Glock barrels as well, you might be interested to know that they don’t just produce OEM replicas.
They also make completely unique barrels that stand out from their factory counterparts.
Lone Wolf’s barrels ditch polygonal rifling in favor of traditional lands-and-grooves rifling. They also offer a number of barrels that convert various Glock models from one caliber to another.
In addition to various threading, fluting, and color patterns, Lone Wolf also produces barrels for nearly every Glock model, including 10mm, .45 ACP, .40 S&W, and .357 Sig models.
4. KKM Precision - Best Precision Barrel
KKM is one of the leading manufacturers of match-grade drop-in Glock barrels.
Designed for competition shooting, KKM’s barrels are a popular choice for Glock owners looking to gain a competitive edge with their accuracy.
Additionally, KKM barrels are also great for shooting non-jacketed bullets as well --- perfect for anyone who has a surplus of lead ammo they’d like to get rid of.
You’ll find that a large portion of the Glock owners shooting with KKM barrels belong to 3-Gun crowds.
This is because KKM barrels are known to improve accuracy thanks to their button rifling, which irons the rifling pattern into the barrel rather than cuts it.
That, and the fact that KKM barrels increased tightness in the chamber is said to give competitive shooters a slight advantage over OEM barrels.
While the KKM barrels might be overkill for a standard home defense setup, if you’re trying to improve your accuracy in a competitive setting using high-quality loads, KKM can do wonders for your grouping.
5. Zev Technologies - Most Versatile
If you know a thing or two about modding Glocks, chances are you’re already familiar with Zev.
This company makes some of the coolest slides and most responsive triggers for Glocks.
But their barrels don’t just come in pretty colors. They're also made with match-grade steel that’s resilient and withstands excessive pressure from shooting with a suppressor.
Features like the unique dimple fluting, recessed target crown, and proprietary broach-cut rifling help make these some of the nicer barrels on the market.

6. Killer Innovations - Best High-End
Looking for a precise barrel? Well, Killer Innovations offers just that.
Killer Innovations' claim to fame is their single-point cutting system for their rifling, which is supposed to produce more accurate and consistent rifling.
We ran in through a couple of builds and also shot different types of ammo at 10 yards. The results were excellent with the compact G19 barrel and frame! See for yourself below!
7. Tyrant Designs Glock Barrel - Best Threaded Option
Tyrant makes a whole bunch of Glock accessories, including some excellent barrels. They only make Glock 19-length barrels for generations 3-5, but they have some neat features.
These barrels feature symmetric fluting for heat dissipation as well as deep crowning for increased bullet stability. Threaded options use the standard 1/2-28 thread pitch pattern for common muzzle devices and suppressors.
Tyrant included a 1 in 10 twist rate for the barrels as well. They are forged from 416R stainless steel, and offered in either a gold titanium nitride or a black DLC finish.
Why Get a Replacement Barrel?
Since Glocks are known for their unparalleled quality, the idea of spending money on an aftermarket barrel might seem strange.
More often than not, people interested in replacement barrels for their Glock want competition-grade barrels that can help increase accuracy when squeezing off rounds.
Many competitive shooters swear by these match-grade aftermarket Glock barrels when using premium ammunition.
Another reason why some people opt for an aftermarket barrel is barrel threading for compensators or suppressors.
With that said, let’s take a look at some popular aftermarket barrels...
Final Thoughts
Glock markets itself as perfection straight out of the box. But that doesn’t mean that you can’t take an already decent design and tweak it to suit your sensibilities!
Switching out the barrel is just one of many things you can do to make your Glock truly one of a kind.
