so, do you use the foaming cleaner on just the chamber or the entire bore? Gunslick doesn't recommend using it on gas operated semi's, but it seems a lot of people do use it to clean AR's.
I bought a can & used it on 2 model 700's, a 30-06 & a 22-250. It got a fair bit of crud out, including copper based on the blue patches, but after 2 treatments I continued to get copper using shooters choice. So I soaked both for about 24 hours & got a lot more out, then gave them a 2nd overnight that didn't get much. Shooters choice also didn't get much, so I'm thinking the stuff is an effective but slow cleaner.
