So I bought a set of sights from a different forum....let's just say the seller was very shady and the admins had to step in just so I could get my sights i paid for! well they showed up and big surprise the rear sight windage has no clicks happening,it feels like I am missing the spring and ball out of there.how do you take the windage screw out? Does it just unthread? Just don't want to damage it by trying to take it apart incorrectly,and I can't find any info on how it comes apart.
