Hey all opinions are welcome.. I need to find something to clean my ar15 barrels with, I will have to see if I can find one of those products local.. Hoppies 9 does nothing for copper removal for me.. I will look at cabelas next time I go for something.. I live in a small town with nothing for decent gun stores..I'm sorry to be the one to disagree, but if you have a bore scope and can see if it cleans or not. I can tell you it's a waist of time. witches brew and butches bore shine is all I will use... just my opinion
