I asked Leupold about this:
There are rumors out there that Mk4 M3 scopes require biased/specific bases. Is this true?
Are Mk4 M3 scopes different in some manner from any of the other Mk4 scopes?
The Mark 4 M3 scopes are just like the other mark 4 scopes as far as application is concerned. The only difference is that the elevation adjustment moves point of impact one full MOA per click.

So I am still confused about this 'built in taper'...
