As I said before it was the butt not the cheek piece photos don't really do it justice but you only have to look at them to realise that it is bending the rear of the cleaning Rod up I don't know if the CZ are mounted higher in the chassis but I doubt it because you wouldn't have much trigger sticking out the bottom this is one of the very early ones maybe the rear of the newer ones doesn't sit so high now , .I don't know.

Again this is on a Howa 1500 223 but I would gather Centreline of bore would be approximately the same for most
Yes mate, it's the same with the Oryx chassis and my CZ457.
I did 2 things...bought a Lowey bore guide, and use a .17 cleaning rod now.
Yes the .17 rod still bends, but it's slimmer and 'bendier'.
Do a final dry out before each match with a pull-through.
It never occurred to me until I saw your photos, that it would be easy enough to whip out a groove along the top of that butt stock to allow the rod to run through nice and straight.
It's only alloy and a patient man with a file (or a Dremel) could do that job in about an hour.
The butt-plate is plain old plastic and rubber...easy as.
You 'might' lose that wee top screw that holds the plastic side plate on, but they are a tiny screw and won't go in too far so should be fine. You will only be cutting about a 1/4" groove along the top.
I recall that the old Martini BSA rifles had a groove cut through their lovely walnut stock for the rod to pass through.
A wee mod I did to mine was to make the thumb rest area a tad fatter. I only shoot rimfire benchrest with my CZ, and I don't fully grasp the pistol grip.
Instead I have my fingers lightly curled around the pistol grip, and rest my thumb out on the right hand side. Makes for a better trigger pull.
Just a wee bit of aluminium, filed to shape, buffed up on a buffing wheel mounted in my drill press, and then glued on with JB Weld.
It's rock solid.
