Optics ready plates for Glock 43X MOS & 48 MOS

The Glock 43X MOS and Glock 48 MOS are slim, carry-friendly pistols that can be upgraded with a red dot optic—but only when you use the correct adapter plate for the MOS cut.

In this category you can find optics ready plates made specifically for Glock 43X MOS & 48 MOS, designed to position your optic securely and keep the fit consistent under recoil.

Why you may need an adapter plate

Different optics use different mounting patterns. An adapter plate bridges the gap between your Glock’s MOS slide cut and your chosen optic, so you can install an optic that wouldn’t otherwise mount directly.

Designed for Glock 43X MOS & 48 MOS (slimline MOS)

These plates are built for the slimline MOS platform. That matters, because plates for full-size Glock MOS models are not necessarily the same as plates for 43X MOS / 48 MOS.

How to choose the right plate

• Start with your pistol: select plates intended for Glock 43X MOS / 48 MOS.
• Pick by optic model: choose the plate that matches your specific optic’s mounting pattern.
• Double-check the hardware: confirm the included screw set and length recommendations for your setup.
