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

Description

For FN pistol owners who want a rock-solid mounting solution for their red dot, the Apex Optic Mount delivers exactly what you need without the hassle. Designed specifically for the FN Low Profile Optics Mounting System™, this mount lets you securely attach any optic with an RMR footprint to your FN slide — including the factory MRD optic cut on models like the FN 545.

This mount bolts directly to your factory slide. No MRD Key Insert is required, so you skip an extra part and potential point of failure. The fitment is precise and purpose-built for FN USA slides, meaning you get a stable platform that holds zero under recoil, whether you’re running drills at the range, carrying concealed, or hunting in tough conditions.

One of the biggest headaches with mounting optics is dealing with liquid thread locker — messy, easy to over-apply, and a pain to clean up. Apex eliminates that problem entirely. Each screw comes with a High-Temperature Thread Locking patch pre-applied from the factory. You simply torque the screws to spec and you’re done. No waiting for thread locker to cure, no risk of it seeping into your optic or slide internals.

At a price point of $70, this mount gives you a direct, no-compromise mounting solution that keeps your optic low and secure. Here’s what you get:

• Direct fit for FN MRD slides — no adapter plates or extra keys needed
• RMR footprint compatibility — works with Trijicon RMR, Holosun 407C/507C/508T, and other RMR-pattern optics
• Pre-applied thread locking patch — skip the liquid thread locker, install clean and fast
• Low profile design — keeps your optic close to the bore axis for a natural sight picture and reliable co-witness with your iron sights
• Durable construction — built to handle the recoil of full-power defensive loads and extended range sessions

This mount is ideal for the practical shooter who wants a straightforward, reliable mounting system. Whether you’re setting up a FN 545 for concealed carry, building a hunting sidearm, or upgrading your home defense pistol, this mount removes the guesswork. You get the same secure, repeatable zero you expect from a direct-mount solution, without paying for features you don’t need.

Drop-in installation, no special tools required, and the peace of mind that comes from a mount that simply works. That’s what you get from Apex — and what you expect from a shop that prioritizes real-world performance over gimmicks.
