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

Description

The Apex Optic Mount for FN MRD Pistols is built for shooters who run their gear hard in the Arizona desert. Designed specifically for the FN Low Profile Optics Mounting System™, this mount lets you securely attach any RMR-footprint optic directly to your factory FN slide. No extra parts, no MRD Key Insert needed — just a solid, direct mount that holds zero through dust, heat, and thousands of rounds.

Living in a suppressor-friendly state means you’re likely running a can. This mount maintains a low profile that keeps your optic clear of suppressor deck height issues, and it won’t interfere with standard iron sight co-witness setups. The direct mount design eliminates the failure point of adapter plates, giving you a more reliable platform for high-round-count training and range sessions.

Every mount ships with screws that have a High-Temperature Thread Locking patch pre-applied. No liquid thread locker required. This means you can install your optic and hit the range immediately — no curing time, no mess, and no worry about screws backing out under heavy recoil or extreme heat. This is especially critical in Arizona summers where standard thread locker can degrade or fail.

• Direct Fitment: Mounts directly to FN slides with the MRD optic cut — works with FN 545, FN 509, and other FN MRD-pattern pistols
• RMR Footprint Compatibility: Accepts all optics using the standard RMR footprint, including Trijicon RMR Type 2, Holosun 407C/507C/508T, and similar
• No Adapter Plate Needed: Eliminates the extra height and potential wobble of plate systems — optic mounts flush to the slide
• Pre-Applied Thread Locking Patch: High-temp formulation resists heat soak from suppressed fire and desert sun
• Low Profile Design: Maintains a clean, snag-free profile that works with most holsters and suppressor-height sights
• Price: $70 — direct, straightforward upgrade for your FN MRD pistol

This mount is built for the shooter who needs a repeatable, heat-stable optic mount that doesn’t add complexity. Whether you’re running drills in 110°F heat, shooting suppressed, or just want a cleaner optic setup on your FN, this mount delivers. No shims, no plates, no liquid thread locker — just a direct, secure mount that stays put.

Compatible with FN 545, FN 509, and all FN pistols featuring the Low Profile Optics Mounting System™. If your slide has the MRD cut, this mount fits. Simple, reliable, and
