NEVER FORCE SOMETHING, you could break the extractor, theoretically. I know that on an Enfield it will pop over, but they were made to do that. I know that it can be setup for the extractor to pop over the edge of a chambered cartridge but I don't know if this was done on the CZ's, if I am thinking right it takes adjustment to the extractor and the slot that it is in so that it has some room to move to the right and get over.

I have a springfield that is being setup and that was something that was getting worked onr ecently, closing it on one in the chamber and the extractor popping over.

this is good for fast loading. otherwise you haev to pop it under the rails and then run it forward. hopefully others that have worked on the cz will reply or somebody that has one and has had it modified to letit work like that.

The CZ uses a true 98 extractor. You have to exert a good deal of pressure on the extractor rib to get it to flex over the rim. You also have to be turning the bolt into battery at the same time.



Until you get the hang of it, try holding the rifle and turning the bolt. Have a friend pinch the extractor while you are doing so. After you see and feel how it works, you can develope your own technique.



1. Never push a true 98 extractor over the rim of a cartridge without flexing the rib. You will only cause more problems.



2. Never modify a true 98 extractor to pop over a rim without flexing the rib. You will only weaken the claw and invite failure on extraction.



This being said, the concept of flexing the rib was developed using standard mauser cartridge rims. I do not have any first hand knowledge of how well it works with artillery shells.
