Excellent Product! I sent several bottles of Super QCG to my son who is serving in Iraq. He is an Infantryman with the 128th Infantry, 1st Infantry Division. He raves about your product and how after using it his weapon functions better and is easier to maintain. The environment he is living and operating in is very damaging on all of his equipment, however he will trust no other product for his weapons care. Thank you for such a fine product.
