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 Or 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.

    Glock 45 optic milling

    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!

    Optic Milling for Glock 30

    Posted by Ed Weber on Aug 3rd 2019

    I had Primary Machine mill-out my Glock 30 to install a Vortex Venom. Excellent work! I received it back three weeks after sending it to them. They went the extra mile and called me to change the milling option; saved me $30. Thank you Bruce. (My G30 didn't need to have a new rear sight notch milled in front of the optic.) My only regret is placing my order on July 3rd before receiving Primary Machine's email offering a 15% discount; missed it by 90 minutes.

    Simply amazing

    Top notch quality and worth the wait. The RMR fits perfectly. The tolerances are so tight, I'd feel comfortable shooting it without the screws. If you're debating between Primary Machine and another company, do yourself a favor and stick with Primary. You won't be disappointed.

    Sent 2 slides to be milled for the same optic. Bruce called me and went over the process of switching optics. Customer service is outstanding. Slides turned out great. They’ve earned my future business.

    Optic milling for Delta Point Pro

    Posted by Ethan on May 30th 2019

    Primary machine did an excellent job on my g17. The milling looks absolutely perfect with a tight fit on the optic and back up iron sights. The slide cerakote job also looks great. Upon taking the gun to the range, I found that the irons were dead on and I could easily use them even with the tall leupold sight. The optic was zeroed in within two minutes and was a blast to shoot.
