Double check your torque. You may have too much clamp up force/pressure due to the torque. On my Vortex scope, the tech recommended torque for the rings that were lower than Burris. If the mount is not defective, front and rear, left and right should have the same amount of gap. Also the bell housing where the turrets or elevation and windage adjustment is too close to the rear ring . Too much clamping force is enough to affect the internals as explain by the tech especially when the ring is too close to the bell housing.

Looking ar your pictures, you have a gap right side of the front ring and a gap on the left side of the rear ring. This maybe enough to affect your scope as the rings are placing a twisting load on the tube. Try getting the gaps even and maybe check with Leupold if they have a recommended torque.
