Running an RMR on your Glock 20 or 21 doesn't mean you're married to it forever. The Brownells RMR Slide Cover Plate for Glock 20/21 is a straightforward aluminum cover that fills the optics cut when you want to ditch the red dot and go back to irons. Whether you're swapping between setups for different shooting disciplines or just need a clean, protected look when the optic comes off, this cover keeps your slide looking finished and your RMR cut protected from dust and debris.
Made from lightweight aluminum and finished in anodized black, the cover plate matches all current-production Brownells RMR-cut slides for these platforms. It's the kind of simple, no-fuss accessory that makes sense if you're running optics one day and irons the next—common enough among serious Glock 20 and 21 users who reload and train across different scenarios.
Installation uses the same fasteners that ship with your Brownells RMR-cut slide, so you likely already have what you need on hand. Just swap the optic for the cover plate and you're done. It's a small detail, but it's the kind of thing that separates a well-maintained gun from one that looks like it's missing parts.
| Brand | Brownells |
| Firearm Compatibility | Glock 20, Glock 21 (Brownells RMR-cut slides) |
| Material | Aluminum |
| Finish | Anodized Black |
Yes, this cover plate is designed for Glock 20 and Glock 21 models with Brownells RMR-cut slides. It will not fit standard, uncut slides.
The cover plate uses the same fasteners that come with Brownells RMR-cut slides. Screws are not included with the cover plate itself, but if you have an existing Brownells RMR-cut slide, you already have the hardware needed.
This is ideal if you run iron sights on your Glock 20 or 21 and want to protect the RMR cut when the optic is removed, or if you're rotating between optic and iron-sight setups without a permanent mounting solution.
