I just mounted a new Bushnell 6-24x50 FFP and put the sun shade on it but put it in a little too tight and when I tried to take it back off I noticed it was spinning the first 2 rings on the scope off as well so I looked inside and I noticed the glass was spinning with it so I just tightened it back up and thought I was fine but then remembered about how the scopes are nitrogen filled and sealed so I was wondering if this was enough to break that seal? I probably got 2 full turns on it max before I realized and tightened back up.
