Trijicon Ac32126 Rmrcc Mount Plate Black 7075 Aluminum Fits Glock 43X/48

The Trijicon RMR®cc mount plate is a precision adapter designed specifically for shooters running a red dot on a Glock 43X or 48 with MOS (Modular Optic System) cuts. If you're building a compact, carry-ready pistol with optics, this low-profile plate serves as the interface between your RMR®cc footprint optic and your slide — it's the critical link that keeps your dot zeroed and reliable through thousands of rounds.

Built from 7075 aluminum, this mount plate strikes the balance between durability and minimal weight addition on a gun that's already optimized for carry. The matte black finish blends seamlessly with modern pistol aesthetics and won't snag during reholstering. Trijicon engineered this plate to sit low on your slide, preserving your sight picture and keeping your overall profile compact — important when you're relying on a defensive or carry gun to stay comfortable in an IWB or appendix setup.

Installation is straightforward: the package includes the mount plate, two mounting screws, and a hex key to torque everything to spec (16 in./lbs). Weighing just 1.1 ounces, it adds virtually nothing to your gun's heft while providing a rock-solid foundation for your optic. Whether you're setting up your first carry gun with a dot or upgrading an existing platform, this Trijicon adapter is purpose-built for the job.

Frequently Asked Questions

Will this mount plate work with my RMR®cc optic?

Yes — this plate is specifically designed as an adapter for RMR®cc footprint optics on Glock 43X and 48 MOS slides. It provides the direct interface between your optic and your slide.

Does this fit the standard Glock 43X or only the MOS version?

This mount plate is engineered for Glock 43X and 48 models with MOS (Modular Optic System) cuts. Standard slides without MOS milling will not be compatible.

What's included, and do I need any other tools to install it?

The package includes the mount plate, two mounting screws, and a hex key. You'll need to torque the screws to 16 in./lbs during installation — a small torque wrench is recommended for precision, though many gunsmiths and armorer services can handle the job if you prefer.

How much weight does this add to my carry gun?

The plate weighs just 1.1 ounces, making it negligible for carry guns optimized to stay light and concealable.
