Many say these are not easy to install. On a CZ 82/83 you will need a #47 drill bit (which I purchased for about 75 cents at a local tool store) and should be able to re-use the factory front sight roll pin, I picked up a couple of new roll pins from CZ-USA. You will also need a brass punch and hammer. Really basic do-it-yourself gunsmithing. I had no problem in removing the old sights and installing the Meprolight sights. If you have any mechanical ability at all you should not need a gunsmith to intall these sights on a CZ82/83
Pros: High Visability
Cons: None
