NF OPTIC PLATE RMR/507C SIG P320 BLK

When you're running a SIG P320 and need a clean optics solution, the right mounting plate makes all the difference. Night Fision's RMR/507C plate is engineered to lock your red dot down without fuss—and if you're sourcing it through Vallejo or the broader Bay Area, TacticCAL in Sunnyvale handles FFL transfer in Sunnyvale for parts and firearms alike.

Slide Plate Fit and Optic Compatibility

This plate is purpose-built for the P320 slide and accepts both RMR and 507C footprint optics—two of the most common red dot formats on the market. The engineering here is straightforward: a single mounting solution that handles multiple proven optics without adapter stacking. If you're cross-shopping parts or transferring firearms through California, our California gun-buyer FAQ covers the compliance side so you can focus on the gear. Browse our gun shop.

Frequently asked questions

Will this plate fit my RMR or Holosun 507C?

Yes. Night Fision designed this plate to accept both RMR and 507C footprint optics. Verify your specific red dot model before ordering, but these two platforms cover the vast majority of compact pistol optics.

Does this mounting plate add significant height to the slide?

The plate adds minimal stack-up over the slide. RMR and 507C mounts keep the optic axis reasonably close to the bore, making cowitness sights optional rather than mandatory on most P320 builds.
