Understanding the FN 502 Optic Footprint: Enhancing Your Rimfire Pistol with Red Dot Sights

The FN 502 Tactical is a groundbreaking .22 LR pistol, notable for being the industry’s first slide-mounted, optics-ready rimfire handgun. A key feature of this model is its compatibility with various red dot sights, facilitated by its versatile optic footprint. Understanding the FN 502 optic footprint is essential for users aiming to enhance their shooting experience through the integration of micro red dot (MRD) optics.​

FN 502 Optic Footprint Compatibility

The FN 502 Tactical features a factory-milled slide inspired by FN’s patented Low-Profile Optics Mounting System™, allowing for direct mounting of MRD optics without the need for a gunsmith. This system supports multiple optic footprints, providing users with flexibility in their choice of red dot sights. Specifically, the FN 502 Tactical includes three polymer mounting plates compatible with the following MRD footprints:​

  • Trijicon RMR: A widely used standard known for its durability and reliability.​
  • Shield RMS: A compact and lightweight option favored for concealed carry and competition shooting.​
  • Docter/Noblex: Another prevalent footprint compatible with various red dot sights.​

This compatibility ensures that users can select from a broad range of optics to suit their preferences and shooting requirements. ​

Mounting an Optic on the FN 502 Tactical

Mounting a red dot sight on the FN 502 Tactical is a straightforward process:​

  1. Remove the Slide Cover Plate: Unscrew and detach the existing cover plate on the slide to expose the mounting area.​
  2. Select the Appropriate Adapter Plate: Choose the polymer adapter plate that matches your optic’s footprint (e.g., RMR, RMS, or Docter).​
  3. Install the Adapter Plate: Secure the adapter plate onto the slide using the provided screws.​
  4. Mount the Optic: Place your red dot sight onto the adapter plate and fasten it securely with the appropriate screws.​

This modular system allows for quick and easy installation of various optics, enhancing the pistol’s versatility. ​

Considerations When Selecting an Optic

When choosing a red dot sight for the FN 502 Tactical, consider the following factors:​

  • Weight: Heavier optics may affect the slide’s cycling, potentially leading to malfunctions. Opt for lightweight models to maintain reliability.​
  • Durability: Select an optic that can withstand the recoil and environmental conditions typical of your shooting activities.​
  • Battery Life: Longer battery life reduces the frequency of maintenance and ensures readiness.​

Users have reported successful experiences with various optics. For instance, one user mentioned running a Holosun red dot sight on their FN 502 Tactical, complemented by a flashlight/laser combo, and achieving reliable performance over thousands of rounds. ​

Conclusion

The FN 502 Tactical’s adaptable optic footprint significantly enhances its functionality, allowing shooters to customize their setup with a variety of red dot sights. By understanding the compatibility and proper mounting procedures, users can optimize their shooting experience, achieving greater accuracy and enjoyment.​
