📚 Frequently Asked Questions (FAQ)

Q: What are the most popular FN accessories in 2024?
A: Red dot plates (for RMR and Holosun), Apex flat triggers, and DPM recoil kits are top sellers.

Q: Can I mount a red dot without milling my FN slide?
A: Yes. If your slide is optic-ready (509 Tactical, Reflex MRD), use adapter plates. If not, use a dovetail mount from EGW.

Q: Are FNX and FNS accessories still available?
A: Absolutely. We carry optic mounts, sights, and recoil systems for legacy models.

Q: Will FN 509 accessories fit the 510 or 545?
A: Most optic plates and holsters are cross-compatible between the 509, 510, and 545 platforms.
