I have a Ranch Rifle, but this question is not about the Ranch Rifle. I am interested in a detailed description of the sights on a STANDARD Mini 14. I would like for someone to describe to me in detail how these sights are adjusted? What tools if any are required? Do the sights have positive CLICKS? If so, how much does each click move the point of impact at 100 yards? Are the sights adjustable for both windage and elevation? Where are the adjustment screws/knobs/dials? If I have left anything out, please feel free to answer questions not yet asked. Close up pictures of the sights and the adjustment points would help tremendously if anyone is willing to break out their digital camera for me or already has some pics on file somewhere. Thanks in advance!
