Shooting corrosive 7.62x39 in an AR...cleaning considerations?

Considering gas comes right back into and acts on the bolt carrier, I flush everything (BCG, lower, upper and buffer assy) with hot water from the tap and then compressed air to dry. I’ve converted the AR over to non-corrosive for the most part due to this. If I do run corrosive, it will be for a long day with lots of blamo down range.
I think he’s thinking/referring to the gas tube.

I've been shooting corrosive through my Wyndham x39 for the past two years. I pull my bcg and rinse it, as well as run some hot water through my chamber and down the barrel. I then pull through and leave it dry. No corrosion, even on the Wet Coast.
The gas tube is stainless, and operates at a very high pressure/temperature. It's nigh impossible to clean, so I just plan to replace it in a few years if it happens to rust away. They're cheap...

The gas tube is stainless and not really much of an issue. The BCG is carbon steel and needs to be cleaned of powder residue in a reasonable time, just like an SKS or vz58/858. Same for the barrel, even if it is stainless. It is easy to clean and I like to not let the bore rust up on my rifles. Use a cleaner like Ballistol that deals with the corrosive salts and you will have few problems, especially since you live in southern Alberta and our humidity is often so low that corrosion can't even start let alone progress rapidly.
