CZC shows needing a 5.5mm front with that sight which should be what your oem sight is.
the front dovetail should be 2mm deep that would leave 3.5mm from top of slide to top of sight.
3.5mm = .137" so you should be good with a .130 sight.
Amazing. Thank you Mick. The depth of 2mm for the front dovetail was the missing number I was searching for. Thanks.
EDIT: Here's the math I came-up with thanks to Mick. The rear CZC PCR tactical sight requires a 5.5mm high front sight (total height) of which 2.159mm (.085") is the dovetail. That leaves 3.341mm (.1315") in height from the slide.
.1315" compared to Dawson's height of .130" is pretty darn close.
To do the math in reverse. The height of the Dawson is .130" from top of slide. To that, add the dovetail depth of .085" and you get a total height of .215" or 5.461mm which is pretty darn close to 5.5mm.
