Eliminate rifle "cant" with the direct attach bubble level designed specifically for the Gray Ops CNC Precision Scope Mount.  When attached via our tight locking V-Groove design, this bubble level is visible just over the left or right side scope parallax/windage knob when viewing through the scope.  Making it easy to stay in the scope and still view the bubble level.  Mounts on either the left or right side of the ring accommodating both left and right handed shooters.
(mounting screws included)
