SilencerCo AC5335 Glock 17 G5 Threaded Barrel 5 9MM Black Nitride Stainless Steel AC5335 UPC 816413028810

Product Description

The SilencerCo Glock 17 Gen 5 Threaded Barrel (AC5335) in Black Nitride is a high-precision aftermarket match barrel designed to add suppressor and compensator capability to 5th-generation Glock 17 pistols. Precision-machined to exacting tolerances, this 5.0-inch 9mm NATO barrel serves as a drop-in upgrade that delivers match-grade accuracy while maintaining 100% operational reliability with suppressed or unsuppressed host handguns.

Crafted from premium 416R stainless steel, the AC5335 barrel undergoes a complete Black Nitride (QPQ) finish treatment internally and externally. This advanced coating provides extreme corrosion protection, self-lubricating surface hardness, and superior resistance to friction wear, carbon erosion, and high firing temperatures associated with heavy silencer usage.

Threaded in standard 1/2"-28 UNEF right-hand pitch, the SilencerCo AC5335 includes a matching black thread protector with an integrated O-ring to prevent the cap from backing off during unsuppressed firing strings. Featuring Gen 5 locking lug geometry, this barrel drops seamlessly into Glock 17 Gen 5 slides without requiring gunsmith fitting, offering suppressor owners an ultra-durable, match-grade barrel solution.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct drop-in fitment for Glock 17 Gen 5 and Glock 47 pistols. Threaded in standard 1/2"-28 UNEF RH pitch. Includes thread protector with internal O-ring. (Note: Engineered specifically for Gen 5 locking lug geometry; will not fit Gen 1-4 Glock 17 frames).

1. Ensure the pistol is completely clear, magazine removed, and chamber visually and physically verified empty.
2. Field-strip the slide from the frame, remove the factory recoil spring assembly, and lift out the OEM barrel.
3. Insert the SilencerCo AC5335 threaded barrel into the slide pocket, re-install the recoil spring assembly, and seat the assembled slide back onto the frame rails.
4. Perform a safety function check, then thread your 1/2"-28 suppressor piston, compensator, or included thread protector onto the muzzle shoulder, hand-tightening against the internal O-ring seal.
