A ready-to-run upper slide assembled in-house by 3CR Tactical for the Glock 17 Gen 3. It arrives coated, cut, and built with the barrel and suppressor-height sights installed — drop it onto a compatible frame and you are set. The deep Olive Drab Green Cerakote pairs with a PVD Multicolor “Oil Slick” barrel for a finish that stands apart.

Build Highlights:

• Assembled slide for Glock 17 Gen 3 — barrel and sights installed
• Olive Drab Green Cerakote with front and rear serrations
• RMR optic cut with cover plate installed — run irons now, add a red dot later with no extra machining
• Suppressor-height (tall) sights for optic co-witness and suppressor clearance
• PVD Multicolor / Oil Slick crown-cut barrel

Optic & Cover-Plate Hardware: Glock-pattern screw sizes for reference — cover plate 6-32 × 1/3″, optic mount 6-32 × 7/16″. When installing your red dot, use the mounting kit that ships with your optic (Holosun, Trijicon, Sig, etc.) rather than generic screws.

Fitment & Break-In: Designed for Glock 17 Gen 3 frames. New slides run tight — apply lubricant and rack the slide 200–300 times before live fire. Verify fitment before range use.

PVD barrel coatings wear over time at points of metal-to-metal contact. This is normal and does not affect function.
