Issue with airforce airguns warranty.

I am wondering how has everyones experience with airforce airguns warranty repairs been? I recently sent my gun in due to the breach hanging on something internally and gouging it. My gun was 3 months old and had only been shot 3-4 times. It was in brand new condition when I sent it in. When I received it back it looked like my lower had been placed on a gun that had been dropped, scratched, and abused severely. I contacted Air Force, and they apologized. They sent me a brand new gun immediately! When I got the new gun I was going over it and realized that every screw on the entire gun was loose and one of them was stripped out. I tightened all the screws and going to figure out how to fix the stripped one. Has anyone else had any type of similar experience with Air Force air guns?
