Cleaning the AR Gas Tube

You’re liable to cause more of a problem trying to clean it with some foolish pipe cleaner and getting it wedged.
You will literally never have a legitimate reason to clean it.

Quit f**king with Eugene.
 
Literally just buy a new gas tube if youre that concerned. Theyre $20. Much easier than obsessing over whether its clean.
 
Through work I instructed courses where we ran dozens of ar15’s well up into 75,000-100,000 rounds without ever wasting time cleaning a gas tube. Many other things will fail long before that causes stoppages including: Rubber Extractor D rings vaporizing, Broken bolt lugs, gas key un-staking, broken firing pin retaining pins, broken cam pins and even broken trigger parts. I would usually get a new gas tube around the time throat erosion was so bad that a new barrel needed to be installed. Either that or the upper receiver literally wore out where the cam pin rotated against the aluminum inside the receiver. Basically, don’t worry about the gas tube.

Yes there is. There is also a chance of breaking your pipe cleaner, and plugging it that way. By cleaning the tube you risk a number of negative outcomes. In contrast, there is no possible positive outcome.

Don't do it.
 
As everyone else said you probably don't need to clean it. That said I have cleaned mine with pipe cleaners since the 80's and I have never had anything from a pipe cleaner block or somehow mess up my rifles. If some fibers from a pipe cleaner did stay in the gas tube I am sure the next round fired would just blow it out. I do find carbon on it so I would say it does remove some. Training doctrine in the CF has us do it. So before all you folks poo poo all over me just remember it's an opinion he is looking for so please don't $hit on me for mine.

Cheers

The gas pressure is high enough to extract an empty casing and push the bolt carrier back, it will definitely blow any soot or debris out of the tube. your gas tube will last as long as your barrel if not longer.

I finally got around today to buying some of those pipe cleaner style cleaners for the AR gas tube. I know it may be a dumb question, but is there any chance of pushing crud up into and blocking the hole in the gas block?

There is no need to clean gas tubes.
