Scope bases for Mauser Action

[ScreaminEagle]

I want to get the Talley quick detach mounts for my Alpine Supreme 7mm mag, which is a mauser action. How do I know if it is a small ring, large ring .500 rear, or large ring .860 rear? Help Please!

Large ring is 1.41, small ring 1.30 diameter.

Large ring is 1.41, small ring 1.30 diameter.

Thanks, I assume .500 and .860 rear means the spacing of the rear screw holes

That is correct.
