Will this allow mounting of the holosun 507k x2? Outer impact has an adapter for this site, but it's heavier. The 57 is touchy to the weight of optics — 1 Answer

No. This Ruger Ruger-57 Optic Adapter Plate is designed to fit optics that utilize the Docter/Noblex optic footprint. The Holosun 507k uses a modification the the Shield RMS mounting footprint that requires modification to a plate designed for the Shield RMS/DeltaPoint Pro. Ruger has a Shield RMS plate for the Ruger 57 but states it is not compatible with the 407K and 507K. However, if you were to modify the plate by shaving down the rear indexing lugs and shortening the front two lugs, then you can fit the 407K/507K to the plate. You can find that adapter plate using the following link:
