I have used both for years and like both. When I clean my .223 AR I spray it down the gas tube and barrel then the BCG. Then I run a clean (243) patch down the barrel and it comes out almost perfectly clean. Then I run about 10 more and spray the for mentioned on each of those patches. Still no patches show any kind of carbon or anything. Then I run about 10 dry patches down the barrel and still no dirty patches. They come out looking brand new. When I'm done cleaning I lubricate. What is up with this stuff? I reload with Varget.
