I bought this Discovery scope on amazon a while back.
Amazon Link The magnification ring has always been pretty stiff, so thought I would look for a throw lever. There is an obvious screw on the ring that I took out to see what the threads were, and realized that it's not what I thought it was. It looked more like some kind of functional screw with random indentions on it, like it was meant to hold something in place. I quickly put it back in and tightened it. What is that screw for? Did I mess something up when I took it out? Coincidently the scope doesn't seem to hold zero as good as it did previously.
