Upgrade your Glock 17 Gen 5 with the SilencerCo 9mm 1/2"x28 416R Stainless Steel Black AC5335—a high-quality threaded barrel engineered for shooters who demand better accuracy, durability, and suppressor-ready performance. Made from premium 416R stainless steel and finished in a sleek black nitride coating, this barrel is built to withstand heavy use, harsh conditions, and high round counts while maintaining excellent precision.
Precision-Engineered 416R Stainless Steel Barrel
SilencerCo designed this barrel to the same standards they use for their industry-leading suppressors, prioritizing precision and consistency:
Material: 416R stainless steel – a match-grade barrel steel known for stability, corrosion resistance, and excellent accuracy with 9mm loads.
Black nitride finish – increases surface hardness, improves wear resistance, and enhances corrosion protection while giving your pistol a low-glare, tactical look.
Designed to be “tough enough to hold up under the harshest conditions,” matching SilencerCo’s reputation for duty-ready gear.
If you’re pushing your Glock 17 hard in classes, competition, or serious training, this barrel is built to keep up.
Suppressor-Ready 1/2x28 Threaded Muzzle
The AC5335 comes from the factory threaded 1/2x28, the industry-standard thread pitch for 9mm pistols in the U.S.:
Thread pitch: 1/2x28 TPI – compatible with most 9mm suppressors, comps, and muzzle devices on the market.
Includes a thread protector – a knurled cap that shields the threads when you’re not running a can or muzzle device, preventing damage during carry, holstering, or range time.
Whether you’re building a quiet home-defense pistol, a competition setup with a compensator, or just want the flexibility to run suppressed later, this barrel is ready out of the box.
Optimized Specs for Glock 17 Gen 5
This barrel is specifically made to fit Glock 17 Gen 5 pistols in 9mm:
Compatibility: Glock 17 Gen 5, 9mm Luger
Barrel length: approx. 5.0" – slightly longer than stock to accommodate the threaded section while maintaining excellent balance and sight radius.
Twist rate: 1:10" right-hand – optimized for typical 9mm bullet weights, from lighter range ammo to heavier defensive loads.
Because it’s built specifically for Gen 5 geometry, you get proper lockup, reliable cycling, and a drop-in installation with factory slides.
Accuracy, Consistency, and Reliability
SilencerCo barrels are designed to push performance beyond standard OEM barrels:
Match-grade manufacturing tolerances help tighten groups and deliver more repeatable point-of-impact, especially when shooting with a suppressor.
Crown and bore geometry are optimized for consistent bullet exit and minimal disruption of gas flow—important for accuracy and suppressor use. (Inferred from match-grade 416R stainless construction and suppressor-centric design.)
The black nitride coating reduces fouling adhesion and makes cleaning easier, helping maintain accuracy over long range sessions.
For concealed carry, duty use, or competition, this attention to detail translates into better real-world performance every time you press the trigger.
Built to Pair with SilencerCo Suppressors & Modern 9mm Cans
As a leading suppressor manufacturer, SilencerCo designs their threaded barrels to integrate seamlessly with common 9mm silencers:
Ideal host for SilencerCo pistol suppressors and other 1/2x28-threaded 9mm cans.
Thread spec and shoulder geometry are crafted to help ensure proper alignment when used with quality pistons and mounts (critical for preventing baffle strikes).
Also works well with 9mm compensators and micro comps for competition or faster follow-up shots.
If you’re building a suppressed Glock 17 Gen 5 or a comped competition pistol, starting with a SilencerCo barrel makes setup simple and reliable.
Ideal Uses for the SilencerCo AC5335 9mm Threaded Barrel
This 9mm threaded barrel is an excellent upgrade for:
Suppressor-ready builds – make your Glock 17 Gen 5 compatible with modern pistol silencers and comps without gunsmithing.
