    Every time I start to tighten the screw on my aero precision scope mount the scope seems to turn and is no longer level with the rifle. I start with the scope being level and the rifle is level as well. The rings connect to each other sideway instead of a top and bottom. I do small adjustments to each screw but the scope always ends up out of level. What am I doing wrong.

    Some mounts just do that. You have to turn the scope a bit and try to get the screws tight as the scope rotates level.

    It can be a real pain sometimes.

    Smaller adjustments and try using gorilla tape to hold it in place while you tighten.

    If you have a collimeter (borescope) set the cross hairs level, tighten the scope, note how much it turns. The loosen and set that much to the opposite side and tighten. Also use a torque wrench and increase in small steps. If all else fails only tighten one screw and get it level. That one will hold it while you slowly tighten the rest.

    This^^^ is your issue. As you tighten the screws... it's adjusting the scope in very little increments.

    Just wanted to add that I have seen this issue with almost every scope mount or rings I have used.

    Even regular split rings will do it if you try to do all the tightening on one side.

    I've seen folks use a VERY THIN layer of clear fingernail polish on the bases to "glue" the scope while tightening. Seems to work.

    This.

    Just like torquing heads on a motor, work your way around slowly and evenly.

    You can also try torqueing each screw no more than 25%-30% of the desired torque. And make sure when you start that the gaps between upper and lower halves are even. And always torque in an "X" pattern. Torque a diagonal set on the front or rear ring and the opposite diagonal on the other ring 25% at a time. Continue 25% at a time in the same pattern until done. I seldom have one move if I do that.
    It is kind of a pain though.
