The nut of the equation looks to be updated to a harder metal, which is something I found to be outstanding as I don't have to worry about them stripping out anymore.
As the other reviewer stated, these are a touch bigger, but I did not have to drill them out - just worked the screw in, which I think cleaned out some dust from the holes. And since I received 5 new assemblies, I was able to swap them all out with ease.

When I ordered this I thought I was getting only one assembly as the picture shows, but when I received it, there were five complete sets in the package.They are a little larger diameter than my old screws were, so I had to drill the holes a bit larger on my sight, that's probably my mistake though, I couldn't remember how old my sight was.
All prices are in USD.
