Rifle Scopes AI mount question

Yes they make multiple sizes. I used a medium height one piece spuhr mount on may AIAX to mount a S&B 3-20 and the lens caps kept the forward end just a hair from seating properly. I had to exchange it for a high mount as I wanted to keep the same lens caps. I still need to rotate the 50mm objective cap just off center to make it fit flush. Is the objective touching the rail or is it the lens cap?
