    Ar15 Gas System

    ...one of our gunnies in another thread had stated he didn't own an AR; I commented on what he is missing. But then it struck me, I have never cleaned the gas tube on my carbine. 1000's of rounds and I have never cleaned it!?


    What do you guys do, wait for restrictions to let you know when it needs to be replaced?

    Soak it in solvent (tray)?

    Run a pull-through/bore snake thingie?

    Feel free to chime in on what you guys do to keep your AR's running true.

    Someone once hinted that he might share the secret of gas tube cleaning with me, when I asked the same question in my noobhood.

    I later learned that they are self-cleaning, or at least will likely burn out before they foul up, and that he was taking the piss (is I believe the correct use of the expression)

    I do flush one of them out with ballistol, soap and water - the x39 that I shoot cap(italist) killers in.

    But that's mostly a side effect of my hosing out the entire upper, since I doubt primer salts are going to do much to a stainless gas tube....or to the upper either, for that matter

    Pipe cleaners. But I can't say I ever cleaned the gas tube on the 3 to 4 service rifles I had in my career. With 10s of thousands of rounds thru them. Plus the blank ammo.

    Fire it till the tube is translucent. Heat is natures natural cleaner.

    Yeah the answer is don't.

    Maybe Hose it out if you shoot corrosive.

    I really dunno how you'd get a bore snake through there as it's basically a 90 degree pin hole at the other end.

    They are self cleaning. The gas pressure should blow out any gunk. You can run a pipecleaner down it. The times I have they came out pretty clean. I can't remember ever worrying about the C7s I carried, but that was many moons ago.

    Pipe cleaners but really it's self-cleaning, it gets 65,000 psi of hot gas blasted through it every time you fire.



    CF Armorers will tell you they've seen more rifles dicked up from people running pipe cleaners/qtips and getting them stuck in the gas tube/gas key vs some supposed malfunction that was due to a dirty gas tube/carrier key.

    ....I suppose I should stop cleaning my gas keys, then. It really never occurred NOT to, while I'm scraping carbon out of the carrier and off of the bolt.

    I probably decoke those bits too often as well.
