So, I was talking to an Army Armorer for few mins. I was picking up a pack of pipe cleaners. He quipped, "They are worthless. I've been an armorer for 15 years and never needed to use the pipe cleaner for the AR gas tubes". My main use for the pipe cleaner is to clean the firing pin hole and the carrier key. The firing pin hole cleaning is mainly out of fear of firing pin getting stuck and my range officer declaring my weapon to be automatic. It never happened, so it may be irrational.
Does anyone think cleaning gas tubes with the pipe cleaner is waste of time? I cleaned it few times in last 10 years with a pipe cleaner, but evertime I do it, I think about how small the port hole on the barrel is, even if the damn thing reached all the way. I can't help to think it's a waste of time.
What do you think?
