I believe the scope is level. The gunsmith who modified the bases said he bore sighted it. I haven't had a chance to shoot it or even handle it too much. I got it back the evening before I flew out for work. I do oilfield work so I'm gone weeks at a time. When I get back I'll try and determine if it's level. If not then I should be able to machine it down a bit.
The rifle is in 8x57. Thanks for the link to the other rifle. I tried looking up similar guns when I first got it last year with no luck.
Here is a picture of the receiver ring before the bases went on.
