Will this fit a Holosun HE407c?

Yes, the RMR footprint is an established standard footprint , and any optic built to that standard will fit that footprint. Holosun currently has the HS407, HS507, HS508, and HS509 built to be compatible to the RMR footprint.

If you want a riser for the 510 look for a Picatinny riser from Optics Planet.
