Problem is that this gun is a 2-3K not a 20-30 K gun. Most guns have some problems if you look close enough. My nest to last K-80, which was at the time the second highest grade made, had several issues. They dealt with them as best they could and I got on with life. Ended up selling the gun not because of any issues, I moved onto another direction. Sounds like they made several attempts to make you happy but could not. Only you can be the judge if you were too picky or not.
