You all know that scope bubble levels can be a PIA--You take most any bubble level no matter the price and when you put it on a flat surface--then swap ends--you see they are not very accurate--I found these $9 levels on Amazon and the big selling feature is that it has two set screws Under each end of the level--you can adjust it to get it correct. I like this style as most that go around the scope make it hard to get to the underside fastener with a TQ wrench etc
I placed 8 levels on a surface plate the other day--note the position of the bubbles--then swap ends and wow! Even $$ bubble levels can be off--I think the glass tubes have taper in them --who knows but these levels at least address the issue and let you fight back a little--for the price it is worth a gamble--I like my first one a lot and plan on a few more.
