Jlin222, your 1st 7 posts have been an informative and entertianing read. I personally still don't consider a CZ 550 a mauser though
There isn't a single part on either one that's interchangable without a lathe or mill. The features you mentioned can be found on many actions that don't qualify either.
One thing I would like to add to what you said about the Zastavia actions. While I agree whole hartedly with your commnets on quality. The actions do clean up very nicely and are decent actions for custom builds. If I was left handed and wanted a custom Mauser I would buy one without hesitation. I'm using one of thier "mini" actions for a pretty cool custom .223 that'll probably be the nicest rifle I'll ever own.
