For Trijicon RMR – Apex Optic Mount Screw Set for FN MRD Pistols with an Apex mount for RMR Footprint Optics

Description

For shooters who have installed an Apex optic mount on their FN MRD pistol, this screw set from Apex is a practical replacement or spare parts kit. Designed specifically for FN MRD models using an Apex mount that accepts RMR footprint optics, these screws keep your red dot securely attached where it belongs. At just $20, it’s a low-cost way to avoid downtime if you lose or damage a screw during installation or maintenance.

This set includes the correct screws for mounting your Trijicon RMR or other RMR-footprint optic to your Apex-equipped FN pistol. The screws are machined to the exact specifications needed for a proper fit on FN MRD slides with the Apex mount installed. Using the right hardware matters—improper screws can strip threads or fail to hold zero under recoil. These are built to handle the demands of practical shooting, hunting, and daily concealed carry.

Key benefits for your setup:

• Secure optic retention: Properly torqued, these screws keep your RMR or similar optic locked down shot after shot, even during extended range sessions or training.
• Simple replacement: Whether you’re building a new pistol or replacing a lost screw, this set gets you back in action without hunting for odd-sized hardware.
• FN MRD compatibility: Engineered for FN pistols with the Apex optic mount—no guesswork, no filing, no modifications needed. Fits models like the FN 509 MRD, FN 545, and others using this mount system.
• Cost-effective spare: Keep a set in your range bag or gun safe. For the price of a box of ammo, you have a backup for the most critical part of your optic setup.

Specs and fitment: This screw set is for FN MRD pistols with an Apex mount designed for RMR footprint optics (including Trijicon RMR, SRO, Holosun 507C/508T, and similar). It does not work with factory FN mounting systems or other aftermarket mounts—only the Apex mount for RMR footprints. Includes the necessary screws for attaching the optic to the mount. Torque to manufacturer specifications (typically 15 in-lbs, check your mount manual).

If you run an FN MRD with an Apex mount and a Trijicon RMR or compatible optic, this is the right hardware kit to keep your dot where you need it. No fuss, no unnecessary extras—just the screws you need to shoot with confidence.
