just keep the barrel pointed down and don't stick it in the dirt...
I kind of rack this up to the same type of overkill as gunsmiths have told me for years... more people wear out a barrel constantly cleaning it than shooting it...
I have multiple rifles that I have replaced barrels on, that are chrome moly, but have never been blued.. yet I hunt with them in the rainy season...
to keep them from rusting? I just spray paint clear spray paint over them on the exposed and unexposed parts...everyone else always think they are stainless..
works just as well as putting wax on them or anything else...
just cover the metal surface and keep the interior of the barrel lightly oiled..
