If you held the upper and rotated the tool, and the gap changed, the tool isn't right.
I used a wheeler lapping tool on my vltor. The wheeler tool was a bit too soft. The face was slightly off from 90 deg. It had a slight taper. Luckily, I know a guy with a cylinder grinder. He fixed it so I could fix my upper.
The fit of my upper and Lilja barrel is a little loose too.
