I'll say you got a great deal on a good shooting rifle. I don't know why people don't take care of their equipment either. I really get tired of hearing the whining about having to clean their rifles.
I told a friend one day who was whining that I figured he didn't have to clean his rifle just let it go. But also expect the wife to stop washing dishes and clothing as that is a chore she does way more than you have to clean a rifle. Never heard him whine about cleaning a gun after that.
