I will not pretend I am an expert on Mauser action, but here is a quote I found regarding the Xastava:
"However, whilst miniature, the action of the M85 is most decidedly not that of a Mauser-pattern rifle. First and foremost controlled-round feed, the single most identifiable and important of Mauser action identifiers, is not present here. If anything, the M85’s bolt is somewhat more akin to that of a Sako rifle, albeit with a Mauser style fixed ejector. And secondly, the massive full-length claw extractor that otherwise identifies Mauser-pattern rifles is also absent. Granted, there is a full length lug that runs along the bolt body where the traditional Mauser claw extractor runs, but the actual extractor resides above that lug and is modelled in the simple Sako style."
