Large Rings	Small Rings
Mauser 98, 48*, vz24,vz22 , Turks* , & Commercial Mausers etc..	Models 93, 94,95,96 & Mexican etc...

48* Large Ring but with an intermediate action see actions.
Turks * most are Threaded for the small ring barrel but have the standard length [ long ] action of a large ring Mauser 98.

Action Length

Here's where Mausers get confusing. There was several countries that manufactured various Mauser action rifles other than the large ring and long action. Some with Small Rings and long actions and some Large rings with Intermediate actions. The m48 and 48a [ yugo's ] have a large ring barrel but an intermediate action. The Turk Mausers [ most ] have a small ring barrel but a long action.

The Turks and m48's are nice rifles with great possibilities for sporterizing but there are more parts available for the standard Mauser 98 large ring and long action such as the k98 , vz24 etc.....
