SilencerCo
The SilencerCo AC864 threaded barrel for Glock 17 is a precision-engineered upgrade that opens the door to suppressed shooting. Built from 416R stainless steel with a black nitride finish, this 5-inch barrel features 1/2x28 threads—the industry standard for 9mm suppressors—so it'll mate cleanly with most cans on the market. If you're running a Glock 17 and want to go quiet without wrestling with adapters or workarounds, a dedicated threaded barrel is the straightforward path.
SilencerCo barrels are known for holding tight tolerances and reliable performance across thousands of rounds. The black nitride finish resists corrosion and handles the abuse of suppressed shooting, where the added length and weight shift how a gun handles compared to the factory setup. The barrel ships with a thread protector, so you can keep the threads clean while you're setting up your suppressor or if you decide to swap it off temporarily.
Whether you're building a dedicated suppressed Glock 17, setting up a home-defense gun with hearing protection, or just want the flexibility to run cans at the range, this barrel is a straightforward upgrade. Installation requires basic armorer skills—it's a swap you can handle at home if you're comfortable with your Glock platform.
