I have this sight mounted on my Remington and it seems that the “clicks” on the fine adjustment knob are not working correctly. I got the sight with the rifle several years ago and have not used it very much at all. Was thinking of trying to take a deer with it this year but when turning the knob it doesn’t have distinct click adjustment. It’s as if it’s loose and sloppy. I’m not familiar with this particular sight so it’s possible that a part it broken or missing. So I’m needing some help diagnosing the issue. Thanks
