Glock, Trijicon RMR/SRO, Holosun 407C/507C/508T, Optic Milling

7 reviews Write a Review

This will allow you to mount your Trijicon RMR red dot directly to your standard frame Glock (G17, G19, G34, etc.) No additional adapter plates will be needed. This milling leaves your rear dovetail intact, and we mill this as deep as it is possible to go. As such, you will just be able to see the tips of your factory sights over the base of the red dot with this work, although lower suppressor height sights are better for an actual 'cowitness.' The base of the red dot is exactly .200" over the top of the slide, so any sights taller than that will be visible through the red dot. 

This milling also fits:

  • Holosun 407C
  • Holosun 507C
  • Holosun 508T
  • Trijicon SRO (front of the optic will be at the ejection port if milled between dovetails, would recommend Race Cut if this is your optic, but you will not be able to run iron sights with that cut)

    Clean and quick

    Had my G45 slide milled and Cerakoated. Real fast turn around, and beautiful work. I did need to cycle the slide about 200 times to wear the Cerakote down inside the slide rail so the weapon would lock back on the last round, but I was expecting that. Looks great, works great. Would definitely recommend.

    Trijion RMR cut /Glock 26

    Great job cut low enough I can even see my OEM Glock sights. Having never sent anything off like a gun slide I was a bit nervous…definitely shouldn’t have been. Great Job Brimstone Gunsmithing !

    RMR cut

    Had a Glock 19x cut for an RMR. Beautiful job, and the cerakote finish was a great match to the factory color. Whole process was super quick with great communication.

    Slide milling

    This is the second slide I’ve had milled and cerakoted by Brimstone Gunsmithing. It came to my expectations and they communicated with me throughout the process. I’ll be sending a third slide in the near future.

    Trijicon RMR cut and Cerakote

    Posted by Devin on Dec 5th 2020

    I sent my slide out on nov 14th to get a cut for an rmr and to get the slide cerakoted black. I received my slide back on Dec 2nd and it looks brand new and the cuts are clean. I work at a gun range in NJ (Gun For Hire) so I been recommending a lot of people to get their slides done by brimstone, you won’t regret it.

    Outstanding experience!

    Perfectly clean matching slide cut finish. Excellent cerakote. Phenomenal turn around time of less than a week which can only come from experienced gun smiths.

    Sent my G17 slide in for an RMR. Had it back in 4 days!!! Tight, snap fit to my RMR, cerakote was great. Will send them another slide in the future!
