Model: All Generation & Model Glock (No 42. 43 Is Milled For Shield RMS Or J POINT Only)


Service: CNC Mill Slide For Optic (Optic MUST Be Sent With Slide - No Exceptions)


Finish: Cerakote Or Black Nitride


Other: We mill precision pockets for your optic! While many companies will mill an over sized "one size fits all" pocket, ours is precision as per your optic. The cycling of a pistol slide is not gentle. The last thing you want is all that force to simply be on the mounting screws due to an optic pocket milled too big! Screws have been known the shear and break over time due to improperly milled slides.

Configurations For Co Witness Sights Using Suppressor Height Sights:

Trijicon RMR Holosun 507, Vortex Viper: Optic can be milled in front of rear dovetail or have rear dovetail milled out and mill new Glock dovetail in front of optic.

Vortex Venom, Burris Fastfire III, And Deltapoint Pro: For lower 1/3 co witness, you MUST mill out the rear dovetail and mill new glock dovetail in front of optic. You MUST use plain black suppressor height sights.

If you are not worried about iron sights, any configuration is fine.

    Fantastic work done by Primary Machine.
    Web site was easy to use, directions were clear and concise on placement of Optic, as were shipping directions.
    Will definitely use Primary Machine again to do next build.

    G19 optic milling and cerakote

    Posted by Josh on Oct 14th 2019

    Excellent job! First time using PM and no disappointment here. Existing cerakote was cleanly removed, optic milling for Holosun 507 was extremely precise and cerakote finish is some of the best I've seen. I'll be looking to use PM again for my G34 slide milling.

    Glock 45 optic milling

    Posted by Paul Herbst on Aug 4th 2019

    This is the second pistol I have sent to Primary Machine for optic milling. I am very happy with the results and will highly recommend them and will probably have another slide milled in the near future.

    Thank you, Primary Machine!
