Running a suppressor on your Glock 43 or 43X means you need a threaded barrel built to handle the job—and the SilencerCo AC5049 threaded barrel for Glock 43 is engineered to do exactly that. SilencerCo doesn't just make suppressors; they've extended their quality standards to barrels because they understand that a suppressor is only as good as the platform it's mounted to. This barrel gives you the 1/2x28 thread pitch your suppressor needs while delivering the durability you expect from a serious suppressor manufacturer.
Built from 416R stainless steel and finished with black nitride, the AC5049 is made to endure hard use and harsh conditions. The 416R stainless steel core resists corrosion and wear, while the nitride finish adds a protective layer that stands up to repeated shooting, cleaning, and the elements. Whether you're running subsonic rounds at the range, hunting with a suppressed setup, or training with your carry gun, this barrel maintains the tight tolerances and reliability Glock shooters depend on.
Compatibility is straightforward: this barrel drops into Glock 43 and 43X platforms and is threaded to accept 1/2x28 suppressors. If you're already running a suppressed Glock or planning to add one, this is the barrel you need to make it happen safely and reliably.

- 416R stainless steel construction for corrosion resistance and durability
