Glock 17 Gen 5 – Flush & Crown Barrel – 9mm – 4.4"

PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

Made by Zaffiri Precision, this Flush & Crown barrel is a Gen 5-specific drop-in upgrade for the Glock 17. It keeps the muzzle profile clean (flush with the slide), adds a proper crown for consistent accuracy potential, and uses quality 416R stainless construction with heat treat for hard use—built to run, not just look pretty in photos.
