you should try a differant, known good scope dude. if your gun is out of warrenty then it sounds like you had it a while. unless you droped it or fired it with the barrel open or did some other damage then you should not assume that the barrel is crooked or bent. If you really are convinced the barrel is bent or out of alignment, you could probly put a straight edge on it like a yard stick on the part that the scope rail is on and measure to see if the barrel is the same distance away from the yard stick on both sides...personally, i would more likely think you have a bad scope. The stock scopes that come with those guns and most other guns are made in china junk. Otherwise they would have a reputable scope makers name on them. Do yourself a favour and go buy a decent scope and rings and try that. If it is straight with the iron sights then it should be straight with a scope.
