We can say that the features that makes an action a Mauser are;
- controlled feed chambering (the round head is held between the bolt head and the extractor claw when chambering)
- Two opposite (180 degrees) locking lugs
- A non-rotating blade type extractor
- Staggered column magazine
- A bolt schroud wich closes the rear end of the action
If you find these on an action, then you have some kind of a Mauser.
The Montatana action, Husqvarna 1600-1640, all FN M98 based rifles (and all the FN derivatives such as Zastava and Santa Barbara, including the Parker Hale 1000, 1100 and 1200 series), Brno actions, M-17 and P-14 Enfield, Springfield '03, older Heym and on, and on. The most modern of these being the Montana (and there are others..).
On an other hand, most modern push feed actions (including the Rem 700, a derivative of the Rem 30, itself a M-17 Enfield) are Mauser derivatives. The Mauser action is definitely the action that marked history.
