A lot of you are saying an hour, that makes me feel better..
Yesterday, like I was saying, I cleaned two rifles. One was an AR. Took me forever to clean it seemed. I've never cleaned one before, and there was so much carbon in the receiver area. I also don't have any special tools like a chamber brush. Just a cleaning kit and a bottle of Hoppes 9 (which seemed to be watered down).
I think I need better supplies. I'm trying to clean a state-of-the-art gun with 1910s technology..
here's a question though, I already saw wear on the parts. Is this just something that happens immediately, or does it means there's not enough lubrication?
Then I cleaned a Garand, which was a breeze by comparison, except for the light rust I found on the outside of the gas system. Came right off with steel wool. I also found a few specks inside in the receiver, and in the corners by the chamber. I don't know how, because it leeched cosmoline when I shot it.
