I just remembered.. you have the CVA Eclipse. Wow that is strange that it would be acting like this. Was this with the XTP's or the maxi hunters it was doing this with? My CVA is actually one of the more stable shooting inlines that I have. Although I am careful not to over heat the barrel. I take two, sometimes three rifles to the range and change over them so the others have a chance to cool down on hot days... My sights do come loose from time to time on my Staghorn. Like already said, be sure and give them a pinch now and then to make sure they are good and solid....
