That's an outstanding way to get what you want from the people that make the guns and understand them. Sometimes getting work done aftermarket by less-than-qualified gunsmiths or even some of us with 10 thumbs, is not only costly with often poor results but a tremendous time sink.
I hope the program goes well enough that other CZs would fall into that process. I'm considering the PCR or the PO1 and would love to have them put on great tritium sights, and trigger parts for a smoother pull. That would be worth the money and time-wait for me.
