Model: All Generation & Model Glock (43, 43X, 48 Is milled for 407K/507K, or RMRcc, 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 507/508: Optic can be milled in front of rear dovetail or have rear dovetail milled out and mill new Glock dovetail in front of optic.

Deltapoint Pro: For lower 1/3 co witness, you MUST mill out the rear dovetail and mill new 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.

    Optic Milling for Glock Pistols

    Posted by Andrew Fuller on Aug 22nd 2022

    I sent 3 Glock slides with Trijicon RMR Type IIs and Trijicon Bright and Tough Suppressor Night Sights. Slides were returned around 4 weeks later with RMRs and irons installed. RMR milling in front of rear sights are precise and exact. Black Cerakote finishes are without blemish. I've shot around 200 rounds through each pistol without issue. I have no hesitation whatsoever recommending or repeating business with Primary Machine.

    If you are on the fence, go ahead and pull the trigger! You won't regret it! The work (optic milling and multicam cerakote slide finish) are absolutely flawless! Primary Machine received my slide on 7/12 and had it in the mail on 8/10. I just received it today and couldn't be happier! I only wish this site allowed you to upload pics. Truly great work!

    Primate Machine always does an excellent job. The fit of the optic to the slide is impeccable.

    Looks better than an OEM MOS slide. Great communication and skillful work. Thank you!

    These dudes are crazy. Optic is hard to take off even when you remove the screws. Had to bang the sight back into place to reinstall, talk about precision. I took the optic off to inspect the work. Looks EXACTLY like the photos depicted. Looks factory. Much respect I will definitely send them more work. Went for the rear in front, about to shoot this right now. Cerakote is also flawless btw.

    Millwork on Glock 19x

    Posted by David North on Jun 27th 2022

    Excellent all the way around. I am very glad to have chosen these guys to do this work. I sent in my slide and Trijicon optic as instructed. They confirmed receipt on 6-10. I had it back on 6-25! They did the millwork and installed new sights and my Trijicon. I am super pleased. Can’t wait to shoot it!

    This is the third one I've had done. Honestly all three have been perfect. Couldn't ask for a better fit and the cerakote looks awesome
