SILENCERCO AC5335 THREADED BARREL FOR GLOCK 17 GEN 5

The SilencerCo Threaded Barrel for Glock 17 Gen 5 (AC5335) is a drop-in replacement barrel machined from 416R stainless steel and finished in black nitride, purpose-built to give Gen 5 Glock 17 owners a suppressor-ready 9mm barrel with a factory-spec fit and the thread pitch to run nearly any 9mm suppressor currently on the market. If you own a Glock 17 Gen 5 and need a quality threaded barrel for suppressed shooting with a direct-thread or piston-mount silencer, the AC5335 is the purpose-designed solution from the same manufacturer as some of the most widely used 9mm suppressors available.

Key Features

• Barrel length: 5 inches
• Thread pitch: 1/2x28
• Twist rate: 1:10 RH

Special Features

• The 416R stainless steel alloy is the same specification used in precision rifle barrels, providing a harder, more wear-resistant bore surface than standard carbon steel pistol barrels while maintaining consistent dimensional tolerances under sustained fire.
• Black nitride finish penetrates the surface of the steel rather than sitting on top of it, producing a finish that resists corrosion, reduces friction during cycling, and does not flake or chip the way some coatings can under extended suppressed use.
• This barrel is dimensioned and lugged specifically for the Gen 5 Glock 17 frame and locking block geometry. Gen 4 and earlier SilencerCo Glock 17 barrels use a different lug profile and will not headspace correctly in a Gen 5 frame, making the AC5335 the correct and only compatible SilencerCo barrel for this generation.
• The 1/2x28 thread pitch is the most widely adopted standard for 9mm suppressor attachment in the current market, giving this barrel compatibility with the SilencerCo Octane, Omega K, and Hybrid series as well as most competing suppressor brands that use a Nielsen piston design.
• The included thread protector installs in seconds and preserves the threads when running the pistol unsuppressed, preventing damage from holster wear, contact with hard surfaces, and general field handling.
• The 5-inch barrel length extends slightly beyond the standard Glock 17 barrel, providing a threaded section that protrudes past the slide for direct suppressor attachment without requiring a booster extension.

Practical Benefits

• Installing the AC5335 converts your Gen 5 Glock 17 into a suppressor-ready host in minutes with no gunsmithing, no permanent modification to the frame, and no alteration to the slide or sights.
• The 416R stainless steel bore holds tighter tolerances over longer round counts than factory Glock barrels, giving handloaders and high-volume shooters a more consistent bore surface to work with across extended range sessions.
• The 1/2x28 thread pitch means you can run this barrel with any 9mm Nielsen piston suppressor or tri-lug mount, including the SilencerCo AC2604 3-Lug Muzzle Device, giving you the option to add quick-attach capability to this same host down the road.
• Suppressor owners who want to expand their host roster without buying a second suppressor will find this barrel gives the Glock 17 Gen 5 full suppressor compatibility at a fraction of the cost of a complete host firearm.
• The drop-in fit means your holster, red dot optic, light, and grip accessories all remain in place after installation, keeping your overall setup consistent whether you are running the pistol suppressed or with the thread protector installed.
• For the Gen 5 Glock 17 owner who wants to run suppressed without compromising the reliability and ergonomics of their existing setup, the SilencerCo AC5335 gives you a capable tool that installs in minutes and holds up across a lifetime of suppressed shooting.

The SilencerCo AC5335 Threaded Barrel for Glock 17 Gen 5 in 9mm is a solid fit for the suppressor owner who wants a precision drop-in barrel that delivers reliable suppressor compatibility and durable construction without replacing the host firearm.
