Answered by Ethan, Gear Expert, from IL, United States, on December 20, 2023

Yes. You would need to use a picatinny RMR pattern mount for your 507C in order to mount it to this NcStar 45 Degree Off-Set Rail Mount.

NcStar does not provide the offset in Millimeters for their 45 Degree Off-Set Rail Mount. I would recommend reaching out to them directly for more information.

If you are attaching this to an existing picatinny/weaver rail and it is installed correctly, there should not be any play.
