A rifle is a piece of machinery. There are no strange voodoo rules about looking after it.
Keep it clean and lubricated and unless it is some piece of Chinese Communist junk it will perform as designed for decades.
I will refrain from posting my opinions on the "never clean a .22" brigade. This is not Whine and Cheese and my bad language may offend.
+1, and to add that I agree that it's bull that overcleaning has ruined more then not cleaning. Neglect is neglect, and the copper brush is far less wear then a copper jacketed projectile. Old wives tales and whatnot.
