I used my Dremel for the heavy grinding and a file to finish it off. The rear posts need to be removed altogether and the front posts need to be shortened to fit the shallow footprint of the 507K. Was told this mount should work with modifications. I wanted to mount the Holosun 507K due to its light weight and very high reviews as to ruggedness and reliability. Please help me finding the right size screws so I can finish installing this sight on my Ruger 5.7 I have a sig sauer Romeo zero sight, I was able to mount the plate and it fits just right but the mounting screws to install the sight on the plate are too short, and these are the screws that came in the kit.
