    You guys clean your guns?
    The carbon builds right back up after a few rounds and seems to be self limiting.
    Scraping the carbon off of the tail of your bolt is about as useful as cleaning out the carbon from the tailpipe of your vehicle........
    This area is self limiting as the carbon builds up and then doesn't build up anymore so a cleaning regimen is not needed.
    all good quotes, i once fussed and fretted over getting all that carbon out, but now i adhere to the, ""This area is self limiting as the carbon builds up and then doesn't build up anymore so a cleaning regimen is not needed.""

    A gun I intend to use for defensive purpose will be as clean as reasonably possible.

    I rarely clean my non fighting stuff... rimfires, 1911, etc. But I am particular about my carry pistol, and fighting rifle.

    my friend's AR apparently jammed up due to carbon in this area

    he was showing it to somebody. checked the chamber, released the charging handle... and CRUNCH. shit was locked up tight

    i guess he managed to pound out the pins holding hte upper and lower together and finally freed it.

    i wasn't there, that's just what he told me

    That must have been one nasty,poorly maintained weapon.I'd recommend your friend read the -10 and learn to properly PM a weapon.
    Ive never,in my 20+ years of shooting AR's had the carbon in that area cause a failure.But there again I do clean and lube my weapons regularly.

    I'd venture to say that 2-4 drops of oil down through the ports of the bolt carrier would have allowed the bolt to close. When I run my ARs in a class or competition, the carrier/bolt is literally dripping of oil........and you guessed it they simply work.

    As I understand, the carbon on the bolt tail is self limiting. The carbon build up inside the carrier may cause some issues. Typically, solvent will disslve a sufficient amount of carbon from both areas. I periodically use a bolt carrier carbon scraper and use a spent .44 mag casing to scrap the bolt tail free of build up.

    Concerning lube--wet wet wet, most issues are caused by people being scared of oil.

    +1 for MOACKS also. As alreadt stated, this area doesn't need to be spotless. If however you do want one that is very clean, then another method that works very well is to use a brass wire brush on a drill press/grinder. Use caution not to damage the gas rings though. It comes off very nicely. Also do not use a stainless wire brush as it is noticeably tougher than the brass ones.

    Its pretty simple....just put a few drops of CLP it the gas ports of the carrier like Gotm4 recommended.
    Thats about the only good use Ive found for the Break Free aerosol CLP.Stick the little tube in one of the vents and give it a shot.It foams up and wets the entire area including the inside of the carrier key.It has a higher solvent content and penetrates like crazy,so it tends to work a little faster than the liquid version.
    If you do this during and especially after shooting the CLP will actually start to break the crusty stuff down.If allowed to sit for a few days it really breaks the stuff loose.
    As far as scrappers and the like for removing the carbon from inside the carrier...personally I dont think its needed and I sure aint spendin my money on a dedicated tool for such.
    All I use for that area is a sharpened chop stick I saved from the china buffet.I eat there about once a week and have collected a good assortment.Free tool and it works perfectly to keep the chunks under control.To resharpen the chop stick just stick it in a pencil sharpener.
    For heavy fouling I either soak the bolt in a jar of CLP or Hoppe's No.9 for a day or so.As a note the ole No.9 works best for soaking.I prefer the smaller glass pickle jars or the old 4oz. Hoppe's No.9 glass bottles.The fouling wipes right off.Same for the carrier.
    Quib has detailed instructions on his bolt dunk solution and it works extremely well also.
    IMHO there is way too much scrapin goin on.
    But if it makes a man or woman feel better then scrape away.
    Thats my opinion as it is anyway.

    i wish i had more info. i wasn't there when it happened.

    i've never had a malfunction like this, and i don't clean my gun much at all. usually just wipe the loose carbon off the bolt/carrier and relube with CLP or militec.
    seems to work fine. every 400 rounds or so i'll give it a decent cleaning.
