I am very interested. I know I am a new guy- but you can check out my ebay purchases (same name) to see I am legit. I would like to install this on my new 6920. Can you confirm it is not a factory "second." I know KAC sells new "seconds" for $150, with either a purple hue or with the L and R lettering on the side rails reversed, or both. Please conrirm it is not a "second" and is in good shape.
