Ever try to get sand out of a pistol, ever try to get sand out of a semi auto rifle? or a shotgun? You own it, you shoot it, its to your advantage to know how to clean it. For example the army taught me how to disassemble and clean the bolt of an AR 15/M16 properly, I listened. You didn't thats why you had to admit to us that you don't know how to clean your AR completely!
