RPM Precision 30mm Scope Rings Low .885" with Bubble Level

A 30mm ring set in the low .885" height with a co-linear bubble level built into the ring. The level sits where you can read it from behind the rifle with your non-dominant eye, so cant gets checked in the same moment you settle in rather than after the shot goes wide.

It earns its keep on the bench too. Mounting a scope square is normally a balancing act with a couple of small levels; having the reference built into the ring takes most of that fiddling out. Ring body and cap are aluminum, the cross bolt and nut are stainless steel, and an alignment lug indexes the cap to the base so the halves close square on the tube.
