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

Description

If you own an FN MRD pistol and want to run a red dot with an RMR footprint, the Apex Optic Mount is a direct, no-hassle solution built for practical shooting, hunting, and concealed carry. At $70, this mount gives you a rock-solid platform without adding unnecessary bulk or complexity to your setup.

This mount is designed specifically for the FN Low Profile Optics Mounting System™. It bolts directly to your factory slide — no MRD Key Insert needed. You get a secure fit that keeps your optic locked in place, shot after shot. Whether you’re running drills at the range or carrying daily, you can trust the mount won’t shift or loosen under recoil.

The screws come with a High-Temperature Thread Locking patch pre-applied. That means you skip the messy liquid thread locker and the risk of over-applying or under-applying it. Just torque to spec and go. It’s a small detail that saves time and ensures consistent retention.

Key benefits for FN MRD owners:

• RMR footprint compatibility — Works with Trijicon RMR, Holosun 407C/507C/508T, and other optics using the same footprint. No adapter plates or extra parts required.
• Direct slide mount — No need for the MRD Key Insert. The mount fits the factory cut on FN USA slides, keeping your optic low and your co-witness clean.
• Pre-applied thread locking patch — Eliminates the need for liquid thread locker. Install it once and trust it stays put.
• Durable build — Machined from quality materials to handle the recoil of defensive loads and high-round-count practice sessions.
• Practical price — At $70, you get a reliable mounting solution without paying for features you don’t need.

Fitment details: Designed for FN MRD pistols with the factory optic cut. Compatible with the FN 509 series MRD, FN 510, FN 545, and other FN USA models using the Low Profile Optics Mounting System. Mounts directly to the slide — no additional hardware or adapter plates required. Remember to verify your optic’s footprint is RMR pattern before purchasing.

If you’re looking for a straightforward, reliable way to mount an RMR-footprint optic on your FN MRD pistol, the Apex Optic Mount delivers the stability and simplicity you need for everyday carry, range work, or hunting.
