Trijicon RMR Mounting Kit for Glock MOS Models - Secure Optic Installation

The Trijicon RMR mounting kit for Glock MOS models is the purpose-built solution for mounting Trijicon's proven combat red-dot sight onto your modern Glock slide. If you've invested in a Glock MOS pistol and want to run a reflex optic for faster target acquisition and improved accuracy, this kit handles the mechanical interface so you can focus on the shot.

Glock MOS (Modular Optic System) slides come ready to accept optics, but they need the right adapter plate and fasteners to secure a Trijicon RMR properly. This kit includes everything you need: a precision-machined sealing plate, short mounting screws sized for the MOS footprint, and the correct hex key for installation. The black-finished plate and screws blend seamlessly with your slide while delivering rock-solid hold zero. Since the RMR comes with longer screws designed for different platforms, this kit ensures you get the right fasteners for your Glock—compatibility that matters.

Installation is straightforward if you follow the included guidance and use the proper hex key. The sealing plate fills the MOS recess and protects the slide while the short screws thread in clean without interference. Whether you're setting up a carry gun, duty pistol, or range shooter, the RMR mounting kit eliminates guesswork and gives you a stable platform for one of the most trusted red dots on the market.
