I was curious how tight my action was so I measured some areas and was surprised at what I found.

The clearance between the bolt and the receiver is right around .0005". No typo, it really is that tight.

The bolt face clearance is .009"and the bolt face recess is .035, so the headspace is .044".

I have not measured anything else yet, but I was blown away by how tight the bolt is. CZ was right when they said better machining and tighter tolerances.
