Has anyone borescoped a barrel after using the boretech carbon remover? I have seen pictures after eliminator but not their carbon specific cleaner. Im trying not to use alot of jb's in my new rifles. I have run a 4mm headed camera down the barrel byt the close up focus isnt great. It looks good especially if i put a patch facing the camera but im not 100% convinced the hard carbon is being kept under control. Thanks
