Apex Optic Mount for FN MRD Pistols to mount RMR Footprint Optics

Description

The Apex Optic Mount is designed specifically for FN MRD pistols, allowing you to securely attach a red dot sight with an RMR footprint directly to your factory slide. This mount works with the FN Low Profile Optics Mounting System™, including the MRD optic cut found on models like the FN 545 and other FN MRD-ready pistols. It replaces the need for an MRD Key Insert, mounting straight to the slide for a clean, low-profile setup.

Living on the Florida coast means dealing with salt air, humidity, and sand. This mount is built with a corrosion-resistant finish to hold up against those conditions, so your optic stays solid whether you’re at the range, on the boat, or carrying daily. The included screws feature a High-Temperature Thread Locking patch pre-applied, which means you can install it without needing liquid thread lockers. That saves you time and avoids the mess or risk of over-application that can creep into internals.

Key benefits for your carry setup:

• Direct slide fitment: No extra plates or adapters needed. The mount bolts directly onto your FN MRD slide, keeping the optic low and reducing the chance of snagging during a draw.
• RMR footprint compatibility: Works with popular optics that use the RMR pattern, giving you flexibility to choose the sight that fits your eyes and shooting style.
• Pre-applied thread lock: The factory-installed patch on the screws provides consistent, reliable retention without the hassle of liquid compounds. Just torque to spec and go.
• Coastal-ready durability: The corrosion-resistant finish protects against rust and wear from humidity, sweat, and salt exposure common in Florida environments.
• Low profile design: Keeps the optic close to the bore axis for a natural sight picture, and reduces bulk for comfortable everyday carry.

Fitment notes: This mount is specifically for FN MRD pistols with the factory Low Profile Optics Mounting System™ cut. It fits the FN 545 and other models in the FN MRD line. You do not need any additional mounting keys or plates. The mount accepts optics with the standard RMR footprint, including popular red dots from Trijicon, Holosun, and similar brands. Always verify your optic’s footprint matches before installation.

At $70, this mount offers a straightforward upgrade for shooters who want to add a reliable red dot without adding bulk or complexity. It is a practical choice for anyone who carries their FN pistol daily in a coastal environment and needs gear that won’t quit on them. The pre-applied thread lock and direct-fit design mean less time fiddling with your gear and more time
