I have read the posts concerning these sights and did not find an answer, so here goes. How in the heck do I get them on my SA85M? I am having a problem putting the rear sight on. How do I get the sight spring back in? By the way, I bought this from a friend and he had a red dot system on it and I would like to stick with the Mojo's. I have a good gunsmith in Carson City, but if you folks could help me do it on my own so to speak I would be grateful. 
P.S. The instructions are not much help.
