I was surprised at how dirty the gas tube was and how hard it was to get the cleaner in but once you did it pulled out gunk.
I have never cleaned a gas tube in my many, many, years shooting AR rifles. Back in Vietnam, "the WW2 surplus ball powder being used to load the 5.56 ammunition" was neutralized with what was basically chalk. It did create problems. If there is a modern powder being used in the 5.56 today, "that plugs up the gas tube" I have never run into it. If you feel better cleaning your gas tube, then knock yourself out.
