I was in a bit of a rush after getting in from shooting to go hang out with friends yesterday afternoon so I didn't get as involved in my cleaning as I normally do.
I checked the rifle out this afternoon and the head of the piston was rusted, and since it had been sitting inside of the gas tube, the inside of the entrance to the gas tube rusted as well.
So of course I freaked out, sprayed everything down with Simple green (the only cleaner I had on hand), and scrubbed the everloving s**t out of everything with a bore brush (the only scrubby thing I had on hand). I examined the rest of the rifle, found some rust on the firing pin, and a little bit on the underside of the bolt carrier. It all scrubbed away fairly easily (most seemed to be lifted off from just the Simple Green) and I drenched everything in oil. I'm glad the bore was rinsed well.
My question is this: Since there was no pitting or anything that I could see, does this mean the rust was just cosmetic? Is it going to come back? Should I be paranoid and over-clean my rifle from now on when I shoot surplus ammo?
