If you are referring to the one on Auction Arms, I think I am correct in my belief that anything from a German arsenal is a military rifle. The expression "Gewehr 98" is a military term, not applied to civilian products. The spoon shaped bolt handle is a simple modification to perform on a military action.

This one has had more than its share of other modifications, starting with the big dovetail cut in the receiver ring and the three holes on the left side of the receiver for an unidentified side mount and the two holes in the receiver bridge, all of which detract from its value.

I don't see anything wrong with the stock, if you like Bavarian cheekpieces, which I do not, except that it appears to have been heavily refinished, which rounded off the checkering and filled it up with varnish, or whatever finish was used. The barrel has a distinctly military profile and the action screws have locking screws, which are rarely found on civilian actions. Other than that.....

I think you could do better for the price.
