This is for mounting any optic with the RMSc footprint optic onto an applicable Glock®. The RMSc a similar footprint to the Holosun K-series, but uses two extra recoil lugs at the rear of the optic.
A standard RMSc cut will be 0.125” deep into the slide and 0.050” in front of the OEM rear iron sight position. The holes will be drilled and tapped for #6-32 countersunk screws, which will be provided. Depending on the width of the slide, the right screw hole may be drilled into the extractor spring bore, but will be reamed afterwards to ensure proper functionality of your extractor plunger/spring. With that said, if the red dot is removed for any reason once you receive it, note that one screw will be shorter than the other to ensure that there is proper clearance for your extractor plunger/spring.

When shipping your slide, send the complete upper assembly, minus the barrel and recoil spring. This will allow us to verify the fit of the red-dot against the other components (mainly the extractor depressor plunger). If you send the slide with new iron sights, we'll install them for free. DO NOT SEND THE LOWER PART OF YOUR FRAME.
Please send your red dot with your slide. From our experience, every red dot is a little unique. We want to ensure you get the best possible fit.

Masterful Work
The cut itself was superb, just beautifully done. I especially appreciated the pre-sales support and advice in selecting the appropriate cut and optic for a Glock 25. Had I gone with my initial choice RMR I likely would have had problems cycling the .380 direct blowback. Installation of the Angry Bear BUIS was flawless and a perfect 1/3 co-witness. Turn around time was very fast, and communication was great along the whole process. I will be back, this is my go to shop now.
