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

Description

The Apex Optic Mount for FN MRD Pistols is a direct-fit solution for securely attaching any RMR-footprint optic to your FN handgun. Priced at $70, this mount is engineered specifically for the FN Low Profile Optics Mounting System™, ensuring a precise and stable platform for your red dot sight. Whether you are running an RMR, Holosun 407C/507C, or other compatible optics, this mount provides the reliability you need for daily carry and range use.

Built with the coastal Florida shooter in mind, this mount features a corrosion-resistant finish that stands up to humidity, salt air, and sweat. The black anodized surface holds up against the elements, so you can trust your setup even after long days at the beach or on the boat. This is not just a part—it is a long-term investment in your carry gear.

Installation is straightforward, with no need for an MRD Key Insert. The mount attaches directly to the factory slide on FN USA pistols equipped with the MRD optic cut. The included screws come with a High-Temperature Thread Locking patch pre-applied. This means you skip the mess and guesswork of liquid thread lockers—just torque to spec and go. The patch holds firm under recoil and heat, keeping your optic zeroed shot after shot.

Key benefits for your EDC setup:

• Direct fit for FN MRD slides – No adapter plates or extra parts required. Works with the FN Low Profile Optics Mounting System™.
• RMR footprint compatibility – Accepts all major red dot sights using the standard RMR hole pattern, including Trijicon RMR, Holosun 407C/507C, and similar optics.
