Maverick Trs Rail

I bought a Maverick Trs rail. I have a gen 1. And I noticed that with the shroud screwed all the way in the rail would not line up like that lip on the underside was hitting the rail. So I unscrew the shroud buttoned up the rail and screwed in the shroud on till it bottomed out on the rail. Is that ok or has anyone ever experienced this?
