Zaffiri Precision Threaded Barrel for G17 Gen 5 | Spectrum

The Zaffiri Precision Threaded Barrel for G17 Gen 5 gives compatible Glock 17 Gen 5 builds a precision-machined barrel upgrade with Spectrum PVD finish, 416R stainless steel construction, and threaded muzzle capability. This barrel is built for Gen 5 G17-style slides where accuracy, durability, muzzle-device flexibility, and custom appearance all need to work together.

The threaded muzzle is the defining feature of this barrel. It gives the pistol a ready path for compatible compensators, suppressors, and properly matched muzzle devices without requiring a dedicated ported slide-and-barrel system. For a Glock 17 Gen 5-compatible build, that makes this a strong option when front-end modularity matters more than an internal ported configuration.

The Spectrum PVD finish gives the barrel a bold custom appearance that stands out through slide windows, optic-ready slide cuts, and open machining details. Because Spectrum has a multi-tone appearance, each barrel can show natural variation in color shift and patterning, giving the build a more distinctive look than a standard black or stainless barrel.

Machined from 416R stainless steel and manufactured in-house by Zaffiri Precision in Largo, Florida, this barrel is designed for consistent fitment with compatible OEM and aftermarket Glock 17 Gen 5-style components. Conventional rifling supports broad ammunition compatibility, while the threaded profile gives the build room to evolve around a compensator or suppressor setup.

This Spectrum threaded barrel pairs well with Zaffiri Precision slide models including ZPS.2, ZPS.3, Z Series, and IBS configurations where the slide and barrel setup provide proper muzzle clearance. It is a strong choice for completing a custom Gen 5 G17 upper, upgrading an existing slide, or adding threaded-barrel capability to a full-size Glock 17 Gen 5-compatible build.
