Use the Fix It Sticks Scope Jack to quickly and easily level your scope when mounting. Using the level is easy: simply mount the Scope Jack to your rifle's NATO or Pic rail, under your scope. Turn the Scope Jack drive handle (the Scope Jack works with any 1/4" driver) until the lifting arm engages with the flat section of the scope under its turrets. Once the scope is level, maintain pressure to keep scope level while tightening your ring screws.
