My rings don't sit level on my scope base. That is, they are high with a small gap under/between base and ring on side opposite of the clamping plate. On the clamping side, the rings sit down tight against the base. This kind of defeats the purpose of the canting bubbles. I have built in cant unfortunately (in the rings). Could it be a base that isn't the correct spec? The gun is a Steyr SSG with a Steyr factory rail.
