Yeah, really.

I fitted a VZ24 extractor to my CZ550 today.

Provides better grip of the case AND I put a bevel on it and it snaps over the case should it get ahead of the extractor.

The VZ24 extractor is a smidgen shorter than the CZ550 extractor, and took a few hours to fit, but it works. In fact, if I got another one after learning the ropes with this one I am pretty certain I could radically improve the CRF. As it is, it feeds with more certainty than the factory CZ extractor and the snapover feature makes it at least as good as a pushfeed in any event.

With VZ24 extractor in place, the gun feeds sideways and upside down {and rightside up to-boot!

}, and tosses extracted rounds as far as your bolt speed will chuck them!

Also, factory CZ550 extractors cost $35.00. The VZ25 hook cost me $15.00.

And...

I fixed my CZ extractor to snap over dropped in rounds. I simply took it off the bolt, pressed hard on the buffing wheel for a few seconds and replaced it on the bolt. Now it snaps over.

So much for the incredible amount of skill it takes to make one of these things do so...
