Hi, I was looking at using a Butler-Creek stock to replace the wooden one on my Brno ZZK 600.Can anyone tell me if a stock designed for a Mauser 98 will fit the Brno which as we know is a Mauser derivative.Thanks

The only part that the 550 or 600 series rifles has in common with a 98 is the extractor. No other parts are interchangeable.

The action inletting screw spacing is the same, the inletting is not.
