cleaning the AR15

I clean mine by blasting hot gases through it while shooting.

That works for me too.

Clever boy .

You guys not cleaning the gas tubes probably have over gassed guns. The tube builds up with carbon and then you feel the gun is actually running betters because it is no longer over gassed. That is until it is constricted enough that it is under gassed and you get short stroking, or failures to cycle.

The barrel life of an M4 is shorter than the cleaning interval of the gas tube.
It's a non-issue.
There isn't really any harm in it as long as you don't lose anything down the tube, so if you like doing it, crack on, but to imply that we are all having problems that don't actually manifest in physical reality is a misdiagnosis.

Nothin much better that a 500 degree blast of pressurized air.

what exactly are you "scraping" out? the maybe .005" of carbon that the weapon limits to the interior of the gas tube is basically welded to it. not only is it not hurting anything, it's also not coming out.

i suppose blanks, as mentioned, can probably dirty up a gas tube a bit more, but live rounds are going to fix that right up, i'm sure. who the hell fires blanks, though? i haven't fired a blank since i got out.

it's not a bong-stem, holms- no goodies in there.
