Large ring Mauser

[Potashminer]

Not real certain that "small ring" actually used except when discussing the 1.300" diameter Mauser 93/95/96 rifles versus the larger 1.410 diameter of the 98's. Often "small ring" goes with no third bolt lug and #### on closing; whereas "large ring" often goes with third "safety" lug on bolt and #### on opening. I suspect a lot of other rifles have front receiver diameters similar - Rem 788 and 700 is 1.348" -ish, P14 was 1.360"-ish Gets somewhat confusing with Mauser "small ring" 98's which have third safety lug and #### on opening, but with 1.300" diameter receiver...

The 1640 is a small ring is it not? Thanks

Yes, it's a small ring. It's NOT a M98 though. It carries more features of the M94/96/38 than M98. The 1640 action have the breeching system of the M/94/96/38 action, means it uses a stepped shoulder on the barrel sitting at the end of the front action ring. The bolt, itself, uses the front lugs of the M/94/96/38.
They copied the '98 lenght (to handle the '06 lenght), they added a third rear lug, they remodeled the gas venting capability - by adding an angled cut for the ejector bolt bolt release - and they streamlined a M98 bolt shroud

The M/98 have a different breeching system as per the barrel shank sits on an shoulder inside the action. The gas venting system is also slightly different.
