dmsims21, my vltor upper is a little loose and not square and that is why I got the tool. However, like you said, the gap on one side should stay constant as the tool is rotated. This is not happening with mine, so the tool is out of whack. I'm bringing to a shop to have the tool squared up as my lathe is in re-build mode (ie completely disassembled.)
