Ok guys I'm new to this website but I have been lurking around gaining some useful info . But I haven't seen anyone ask this question before. Now to the question, the CZ 527 has a fixed rear sight that is held in with a dovetail, pistol sights also are held in with dovetails... so can I put a pistol sight in the 527's dovetail? The reason would be I want to be able to see the sight at night and I can't with the standard sights, pistol night sights are readily available however.
