With the CZ Custom's PCR Short Tac Rear Sight, they said on the product's description that it is to fit with a 5.5mm tall front sight.
So that raised my question again: If I was to purchase this sight, can I use it with the factory front sight? Is it 5.5mm tall?
If not, on CZ Custom's front sight options, I found the CZ Tritium Front Sight 5.5mm, and here's the description:
CZ 75 Front Sight with Trijicon? Lamp 5.5mm x 3.0mm
5.5mm Front Sight Height. (Measured from Base to top of sight when OUT of the gun)
Trijicon? Front Night Sight Fit all Factory Lateral (Front to back) dovetails.
Genuine Trijicon? Front sight Green Lamp silver outline.
It doesn't say PCR in the description but it does specify "CZ 75", which is what the PCR is.
Idk it's confusing.
