You can fall down the stairs, one step at a time, or you can just face the facts- pull the rear sights and replace them with a blank and get a peep sight for the rear.
Note: I had my CZ's bridges modified/machined to accept Talley rings because I was tired of the limited options the CZ proprietary mount design, left me with. When I decided to use a peep sight, for my old(er) eyes, the modification made my transition, a markedly easier one. The rear peep sight displayed, is made by Talley (for their mounts) and commercially available.
Good luck!
