Features

This aftermarket complete upper for the Glock 17 Gen 5 is engineered to deliver a refined performance upgrade with a fully assembled package that includes a slide, barrel, internal components, and HD fiber sights. Built from a single billet of 17‑4 stainless steel, the slide is machined to tight tolerances that enhance accuracy and reliability while maintaining consistent lockup under sustained use. All components are manufactured and assembled in the United States, reflecting a commitment to precision craftsmanship and long‑term durability.

Each slide receives a Cerakote finish for added surface protection and arrives pre‑cut for a Trijicon RMR or Holosun 507C‑pattern optic, providing immediate compatibility with popular red dot systems. The included threaded barrel expands accessory options, supporting muzzle devices and suppressor setups. This upper is specifically designed to fit the Glock 17 Gen 5 frame, ensuring proper alignment and reliable function with factory‑spec geometry.

With a focus on accuracy, performance, and ease of integration, this complete upper stands among the strongest aftermarket options available for Glock‑pattern builds, offering a ready‑to‑install configuration suitable for both replacement builds and custom projects.
