Hello All,
New Member here. Totally new to AR's. I hate to be the new guy who makes his first post about a problem he is having but I figured you all are the best folks to ask... So thank you in advance. Recently purchased a brand new Colt 6920. Well today when I was cleaning it, I pushed the chamber cleaning brush too deep into the chamber/bore and the steel bristles became lodged in the chamber (the part I believe is chrome lined). Anyways, now I have some noticeable gouges in the chamber from me pulling the brush back out (and rotating it as I did so...oops). I will attach photos of it. One is of the chamber and the other is of the scratches on the bullet from a round I chambered afterwards. My questions are: 1) How bad did I mess this up? 2) Is the rifle safe to fire? 3) Can this be repaired? I realize I am a total idiot. So again, thank you in advance for your patience and advice. http://s1267.photobucket.com/albums/jj546/soloshooter7/?action=view¤t=photo1.jpg http://s1267.photobucket.com/albums/jj546/soloshooter7/?action=view¤t=photo2.jpg |

not sure what your second pic is supposed to be showing so i wont make that one live you dinged that chamber up pretty good... wouldn't think a mild steel chamber brush would do that to a hard chrome finish... I would say it's safe to fire I suppose it could cause some problems with extraction but will probably extract just fine. It shouldn't really affect accuracy in the least. My guess is it will just leave some nice little rings on your brass no big deal if your not a reloader. If it still extracts the cases no problem I'd probably just shrug it off. If it causes problems then you would probably be left replacing the barrel I got a brand new upper before that looked like it was reamed with a beaver I polished it out but don't know that this warrants polishing or if it would even work without making it unsafe. |

Yes, it fit in there alright, it was just getting it out that was hard.
Well anyways, took the rifle to the gun shop where I bought it and they instantly knew what it was. They called it "chatter marks" and have apparently have been seeing it on Colt's lately. Evidently the marks were from the factory, not from me (thats a relief). So they are sending it back to the factory for repair. Anyone have any idea of Colt's factory turn around time? I was told by the guy at the gun shop it would need a new barrel. He also commented that Colt's turnaround time was about 6 months. I'm hoping he was joking... Thanks again for the input |
Heh my chatter mark photo is way worse 
A thread regarding colts turn around time of course this may have been an expedited case due to the severity. op posted the malfunction 6/8 had his rifle back 7/19 so 6 weeks ish http://www.ar15.com/forums/t_3_118/575986_New_Colt_6920_LE_Blew_Up_this_week___.html heres my pics i don't have as good of a camera with a macro like you though

Thanks for the reply Obo. Is yours a colt as well? And are you planning on doing something about the chatter marks?
I was pretty surprised finding them in mine, considering most of the research I did before purchasing the rifle made it seem like Colt is the golden standard of quality and reliability when it comes to ARs. But hey at least mine didnt have a catastrophic malfunction like the one in the thread you linked. Im now wishing I went with the Daniel Defense instead. My friend bought one at the same time I bought my Colt and it is one nice piece. |

Quoted:
Called Colt today... they currently have a 4 month turnaround time for repairs at the factory. The rep said they are very backed up. So looks like I bought myself an early christmas present   . If it was me, and my only AR, I think I'd be buying me a barrel and donig it myself but and the same time making sure that Colt new about the problem.
I hate waiting

Mine is not a colt, it was a cheapo from a gun show. They called the company zero tolerance guys name was joe it was a $289 upper from a gun show here in vegas.
I dealt with the manufacturer for a bit he was an asshole and refused to acknowledge the issue even though it was causing extraction stoppages. The manufacturer sent the upper back with an o ring under the extractor and a loose barrel nut. at first i was just going to replace the barrel ... the new barrel turned in to me building an entire rifle. So what i ended up doing to the one pictured was polishing the chamber. I got a dowel just smaller than the chamber and some emery cloth cut a slit in the dowel for the emery cloth and chucked the dowel in a drill. This took the worst of the ridges out mine actually had raised areas that were grabbing the cases so i was able to smooth those down without increasing the diameter of the chamber. That is not a chome lined chamber so polishing it was possible. It's still not really pretty but it at least extracts and ejects 100% and doesn't leave my brass so chewed up. (I reload so pretty brass is important to me) I started again looking at barrels to replace that one cause I still just have a grudge against it. ymmv hope you enjoyed my story I really just need to save it somewhere so i can copy and paste. |
