The Alpha Dog Holosun 509T optic milling creates a direct mount feature on your Glock slide. With our direct mount milling feature, the adapter plate included with the optic will not be needed. The 509T optic is securely held in place by the front and rear pocket edges, in addition to the picatinny style undercuts. Our direct mount milling feature creates a precision pocket for the Holosun 509T. Unlike others who offer Holosun 509T milling, the pocket we create leaves no awkward gaps in front of the optic.
With our Holosun 509T optic milling, the optic will sit as low as possible on your slide; however, if you are looking for a co-witness with your iron sights, suppressor height sights will still be required. We recommend Ameriglo or Trijicon suppressor sights for those that are wanting a co-witness.
This and all of Alpha Dogs slide milling patterns are 100% CNC machined which increases milling accuracy and finish quality. When a slide is milled, the finish in the milled are is removed which exposes the raw steel. The raw steel will oxidize if left untreated! To avoid oxidation, we recommend having us Cerakote the slide to preserve its integrity.
The 509T optic milling is not available for slim line Glock (G42, G43, G43X & G48)
NOTE: This is only available for Glock slides and is for milling service on a customer supplied slide ONLY. Unless selected as an option above, the milling cost does NOT include slide refinishing. Milled areas will remove the slides coating and expose raw steel which will rust if left untreated.
