I searched and only got a handful of topics that touched on Brunox. What is the US equivalent? I've got all kinds of cleaners and lube, but I can't seem to find Brunox in the US. I found some in Canada, but the site didn't ship to the US. I've got Ballistol, but what is the equivalent to Brunox to use as a replacement? I've got MPro7, Tri Flow, Wilson Combat Ultima Lube, and Break Free. Until I got the Ballistol, I cleaned and lubed with MPro7. I guess I'm most concerned with application on the bolt rails and contact with the polymer frame.
