MAYBE a fix for AR spring chatter.

I totally dissagree, that roll of sand paper will move around enough to start tearing up the inside of the tube, and that will just be the beginning.... If you're comparing this to firing in a sandy or dusty enviroment, you're a little off base on that. What you're talking about is sand from OUTSIDE the closed system of the rifle... Sure it can get in,,, but,,,, You put sand inside yours.........

Yeah, that sand on the sandpaper is bound to come loose, and after that ... 'round and 'round she goes; where she stops, nobody knows. Yikes!
