Does a Kar-98 small ring, long action reciever, have large ring threads ?? I have heard of the Turk; large ring, long action, small ring threads. But was confused when someone mentioned small ring, large threads ?? :confused:

Kar98a's have small rings and small threads. Make sense, right?
Calif-Steve your comment makes perfect sense; however I just saw a reference on the hoosiergunworks site; that states the Kar98 is a small ring, long action with large ring threads ?? So I'm still confused :confused:
I wrote K98a's have small rings and small threads. This is the WWI Pioneer Rifle and was made to be light weight. The WWII rifle, the Kar98k, is a large ring rifle and it takes large ring barrels. It is commonly called the Kar98, but is properly called the Kar98k. By the way, most German WWII rilfes were stamped "Mod98". I hope this helps.
I should think they mean the same thread as...not the threads are bigger. That's not really possible.
Calif-Steve put it a bit more clearly. The confusion arises from the sloppy use of Kar98, when the writer intends to refer to the Kar98k.
However, browningautorifle was understandably still somewhat bothered, as referring to large or small threads is sloppy, when what is meant is the thread diameter. Military Mauser actions have 12 tpi Whitworth-form threads.
That means, threads with a 55 degree included angle, NOT the 60 degree angle of US threads. It seems that using the 60 degree form on replacement barrels is not unknown in the US, but it is nevertheless mechanically incorrect, as this means the threads are not bearing properly on the flanks, but on a more-or-less deformed receiver thread crest. As they say .... it's your funeral.
BTW, the barrel shanks (i.e. thread outside diameters) come in two sizes on military Mausers: 1.1" and 0.98". Yes, inches, nothing in millimetres!
All this goes way back to the 1840s and the introduction of the Whitworth thread system as a standard - a world first, I think. Whitworth thread-cutting gear quickly became standard in Europe - in fact, just about everywhere except Enfield! And, of course, the US, where Mr Sellers and friends decided that they were not going to be dictated to by a load of Limeys and strode briskly forwards in the spirit of "Not invented here" to do their own thing.
