How to tell whether the stock is for small or large ring Mauser?

I got bunch of new sporter stocks from an estate and want to use them to re-stock some of my rifles. They have already receivers drilled for scope mounts, so no regret for bubaizing :)). I have one Chilean carbine that needs new stock. Is there any way to tell if a stock will fit. I would like to know by measurements, rather than trying each of them on the barrelled action. Thanks!|||Nice find!





I have been collecting old Mausers since my dad got one from Sears back in the 70s and I still get confused by the different action sizes, not just small or large ring.





The Chileno is a Small Ring. But get out the calipers and measure the action and screw distance.





Large Ring - Mauser's with a Large ring have a thread shank diameter of 1.10" With 12 threads per inch. Across the face of the receiver will measure 1 3/8 . You can also measure the trigger guard screw holes, From center hole to center of other hole should measure about 7 7/8 or 7.830.





Small Ring - Mausers with a Small ring have a thread shank diameter of .980" With 12 threads per inch. Across the face of the receiver will measure 1 1/4. You can also measure the trigger guard screw holes, From the center of the holes measure , it should measure about 7 5/8 or 7.625.
