Zastava's are a basic mauser 98, but then the Model 70 is also. What you have is a mauser 98 action with a Model 70 safety, so you dont have to mount the scope high to clear the wing safety.
They are good commercial mausers, relatively inexpensive and good value. Largest "problem" with them is plain wood, but you are buying a entry level gun. Most people who buy them are satisfied by the accuracy, however, each rifle is a individual in this regard. Zastava has been building firearms for decades and their firearms were commonly re-badged and sold by other makers much like automakers do today. Common "Z" guns are Interarms Mark X, Remington 798, and i believe Charles Daly.
