I just had a look at that catalogue and the photo is of a 602 (small bolt shroud and reverse safety give it away). Maybe they hadn't done one on a CZ when the catalogue was published. Steep price though - $350. You can get a fully adjustable NECG rear peep for $85 that doesn't require any fitting and is readily detachable as required. Although some folks don't like the look of the ears on the NECG - could file them off I suppose.
