It is a true 98 pattern, will cock on opening and has the third locking lug near the bolt handle. This action is approximately 8.750" long. The third size of actions is the “standard” size action. These are not commonly encountered and original Mauser specimens are desirable to collectors. Each of these actions is unique to the manufacturer and parts are not interchangeable. Magnum-sized, Mauser-type actions have also been built by other manufacturers like Brevex (France), BBK (Korea), and others. These were built in limited numbers by Mauser and are slightly over nine inches in overall length. The fourth size of Mauser action is the Magnum size action. Parts on all four of these actions are for the most part interchangeable bolts, bottom metal, firing pins, etc. The 19 Mexican actions are small ring actions while the 1924 Mexican and Yugoslavian actions are large ring. They cock on opening, have the rear safety lug, and have the 98- style “flanged” shroud on the bolt.
These are also about 8.5" long but have the features of the true 98 pattern action. Slightly less common intermediate size actions are the 1910, 1924, 1936 Mexican, and the 1924 Yugoslavian. These actions have an overall length of about 8.5". The bolt shroud at the rear of the bolt does not have the gas deflection flange of the M98 shroud. They lack the third (safety) locking lug at the rear of the bolt near the bolt handle root and they cock on closing. These are the pre-98- style, small ring Mausers that have the long, non-rotating Mauser extractor, familiar ejector box on the left side (rear) of the receiver and the enclosed staggered-round magazine. The most common of these are the 1893-1895 Spanish Mausers and the 1894-1896 Swedish Mausers. The next size larger is the so-called “intermediate” size action of which there are several examples. These actions are among the most uncommon Mausers, quite rare and highly desirable to collectors. The overall length of the actions is about 8.125".
The bolts, receivers, firing pins, extractors and bottom metal are unique to that model and are not interchangeable with other Mauser actions. These are true 98 pattern actions that cock on opening.
Almost all of these were small ring actions, although at least one specimen of large ring Kurz exists. The smallest factory Mauser actions are the Short, or “Kurz” actions, that were made by Mauser for the commercial market prior to WWII. The large ring action has a slight step or swell at the front of the action and the ring will measure 1.410" across. The outside diameter of the action at the front ring will be 1.3" across. A small ring action has basically the same external profile from front to rear. The term “ring” when it applies to a Mauser action refers to the area at the front of the receiver into which the barrel shank is threaded. The most common actions you will find are known as large ring and small ring actions. While the following guidelines are accurate, they are not to be taken as absolute. Mauser actions have been manufactured by a large number of companies in many different countries for over 100 years. Two of these are rather uncommon and two of them are quite common. There are four basic sizes of Mauser actions.
