I tried BoreTech Eliminator for the first time in my previously cleaned Krieger barrel on an AR-15. I used Hoppes #9 last time as I recall. I dipped a nylon brush in BoreTech, ran it through several times, and then a few patches also soaked in BoreTech. Good Lord, those patches were seriously green! After a 5 minute soak, I ran dry patches through, and on the fourth patch, it was quite clean. Never have I gotten this much copper out, this fast, nor have I ever had the patches be so green to start, and then go clean so quickly. Will see how it does on the barrel without the benefit of Hoppes cleaning it first, but BoreTech does seem to work quite well.
