The Calculated Kinetics CALK ADPTR PLT for Glock MOS to RMR is a drop-in mounting plate designed to bridge your Glock MOS slide with RMR-footprint optics like the Holosun 407C, 507C, and 507 Comp. If you run a Glock MOS pistol and want to mount a red dot without hunting for adapters or making do with loose solutions, this plate handles the job cleanly — it's engineered specifically for the MOS interface and gives you a solid foundation for your optic.
Calculated Kinetics designed this as an improvement over OEM mounting options. The package includes everything you need: the adapter plate itself, mounting hardware, a Torx bit for installation, Vibratite threadlocker, and an install card to walk you through the setup. That's the kind of attention to detail that keeps your optic where it belongs — zero shift, zero wobble.
This plate works with the full range of RMR-pattern optics, making it a versatile choice whether you're upgrading a carry gun, a training pistol, or a competition setup. Note that it's designed for standard RMR footprints and is not compatible with optics that have forward-protruding designs like the RMR HD or SRO. Also, it's built for full-size Glock MOS models — the 43X MOS is excluded from this platform.
| Brand | Calculated Kinetics |
| Product Type | MOS Adapter Plate |
| Optic Footprint | RMR Pattern |
| Compatible Slides | Glock MOS (excluding 43X) |
| What's Included | Adapter plate, mounting hardware, Torx bit, Vibratite, install card |
The Calculated Kinetics CALK ADPTR PLT is designed for any RMR-footprint optic, including the Holosun 407C, 507C, and 507 Comp. It is not compatible with forward-protruding designs such as the RMR HD or SRO.
This adapter plate fits Glock MOS models with the standard MOS interface. The Glock 43X MOS is excluded and will not work with this plate.
Everything needed is included in the box: the adapter plate, mounting hardware, a Torx bit for installation, Vibratite threadlocker, and an install card with instructions. You don't need to source anything else.
Calculated Kinetics designed this as an improvement over OEM MOS mounting solutions, offering a more robust interface for your red dot optic.
