Hi, I'm looking for the name and location of the sprite used in the red dot sights you can put on your guns. I want to make it smaller and potentially restyle it so it's more accurate as I always hated how massive it was in first person. Can someone point me in the right direction?

Like the title says what are some mods that you can use while playing through the campaign that are worth it. Could there be a mod pack that encompasses all of these that's just an easy drag and drop solution?
