hey guys just got my first swfa ss. but i was wondering something i took the scope to my local gun shop to have the eye piece lens cover put on but before i took it down i adjusted the fastfocus to fit my eyesight then took it down when the person put the lenscover on i noticed he was pushing the scopecap on pretty hard now when i turn the fast focus you can feel it grind a little. but the focus does still work i was just wondering if i am just being to paranoid.
