Product Description

- CNC mill your Glock slide for your optic



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.


What to do after you order:

- Print order confirmation email

- Send copy of confirmation email with slide (does not need to be disassembled) and optic to:

Primary Machine

2951 Railroad Ave

Morgan City, LA 70380


Current turn around time is 2-3 weeks.


- We WILL NOT mill deeper than firing pin block allows! 

If you choose to mill IN FRONT of rear dovetail with the following optics, the firing pin block will be a limiting factor on depth, which is .050" deep: DP Pro, FF III, Venom

With that said, those optics WILL NOT co witness unless you choose the option to mill the rear dovetail out and mill new dovetail in front of optic. This allows us to mill the optic deeper and co witness with Ameriglo suppressor height sights. DP Pro will only co witness with plain black front and rear suppressor sights.

  3. Exceeded my expectation 5 Star Review

    Posted by on Jul 13th 2017

    I ordered the installation of RMR on my Glock 19. The finish and workmanship of the slide are superb as expected, and the processing and delivery exceeded my expectation. It is encouraging to know that there are businesses like Primary Machine run by a veteran and driven by quality work. Keep up the great work!

  6. New Life For An Old Pistol And Old Eyes 5 Star Review

    Posted by on Jun 16th 2017

    I have a Glock 21 Gen 3 which I was bored with and I had considered trading it away or selling it. I decided to use it as a test mule for one of those newfangled pistol optics everyone seems to like. I poked around on the AR forums and found that Primary Machine has a great reputation and I decided to have them mill the slide for a Leupold DeltaPoint Pro. This proved to be an all-around good decision.

    Reasonable pricing, fantastic workmanship (looks factory), quick turnaround, and great customer service. Bruce answered some of my e-mails within 5 minutes, and delivery was just a hair over 3 weeks from the day I shipped the slide. And my 55 year old farsighted eyes REALLY like the reticle which appears in the same focal plane as the target.

    Realistically, how many times will the average gun owner swap multi-hundred dollar optics? Do your homework, decide which sight you want, and have the slide milled for it. This is a much better option than the OEM systems with adapter plates, in my opinion, especially for the Delta Point Pro. I can't wait to get back to the range and take some tactical classes with my "old" pistol!

  7. Better Than I expected 5 Star Review

    Posted by on Jun 7th 2017

    Looking at pictures of the work that primary machine does, does not give them justice. I ordered stainless and it came out perfect, just what I wanted. Turn around time was good also, about three weeks.

  8. Awsome Job on My Glock 34 5 Star Review

    Posted by on Jun 4th 2017

    The milling for the rear of the slide to accept the red dot optic looked like factory original. I had the slide coated and the finish was perfect. I recommend sending in the complete slide and red dot for a proper fitting. this was a perfect job...!

  9. Old Eyes and a New Sight 5 Star Review

    Posted by on Jun 3rd 2017

    In competition, an Eotech sight brings my scores up immensely!

    Primary Machine mounted one on my Glock 29, added suppressor sights and Cerakoted it in Stainless.

    Looks great
    Shoots great
    Carries great

    Postal pickup to postal delivery was about a month.

  10. Fine Craftsmanship! 5 Star Review

    Posted by on Jun 3rd 2017

    Great service and the quality of the fit and finish are superb.
    Sent in my G23 to have it machined for a Leupold Delta Point Pro and have it refinished. Unfortuntely the supressor height sight I had provided weren't tall enough to clear the sight, but PM were quick to point me to a set that would work from Dawson. All in all a great job by Primary Machine and would definitely recommend them to anyone looking to get their slide machined.
