I bought a Colt AR15A4 on 11/2014 from TombstoneTactical.com, and the action on it has always been buttery. Today I picked up my Colt 6920 I bought on ArmsUnlimited.com and the action is rough, the bolt fits too snug in the bolt carrier. First I cleaned it, and that didn't help, so I took out my A4 to compare everything, and the A4 is just silky smooth. Two weeks ago I called Colt, and they said they'd ramped up production lately. If I had to guess, it has something to do with the threat Hillary poses to not only "assault weapon" ownership, but to "assault weapon" manufacturing.
If Colt has been mass producing these things, does that explain why my new 6920 (serial number is is 400*** for reference) is rough on the inside, and should I be concerned about quality/functionality? Does firing a weapon enough smooth out the internal components? I run my A4 for 100's of rounds without cleaning it and never had a jam. It seems like my 6920 is more likely to jam because it's rougher and not silky smooth like my A4. I cleaned it and lubed it but I haven't fired it yet. 
(after cleaning) Does it look rusted? 
Can you see how rough it is in there. After cleaning/lubing. When I got it parts were either bone dry or greased. 
What do the numbers mean? 5) Why not C marked? 
WTF?

C stamp is an upper machined by Colt.
Stamps on the barrel are various proofs. My factory 10.3 has a horse shoe and a few other things. The new number stamp reflects their .mil Cage code or a new cataloging system IIRC. Colt isn't known for removing little bits of flash and other imperfections or having the most beautiful rifles. However that said my Colt products have been perfect in function.(sample of me) Probably dirt, preservative grease there in your chamber. Clean the gun and lube liberally. Firing the weapon a lot will break it in of course. Have fun. ETA: number is cage code for Colt Defense COLT DEFENSE LLC Cage Code 13629 W HARTFORD, CT, UNITED STATES |
| The number on the barrel is Colt's CAGE code, and it is their new markings on the barrel. The "C" on the upper Colt's stamp knowing it was a genuine Colt part. The inside of the chamber is normal, so you are fine. My initial 6920 upper was rough, but after shooting it, the action became buttery smooth. I think that is dry lube making the action rough. |

But has it actually jammed? I cleaned it and lubed it but I haven't fired it yet. Oh, nvm. WTF? It's a 6920...shoot hell out of it and get back to us (i.e. it's perfectly fine). I'd bet you could run that gun for 10,000 rounds w/o cleaning it and it would be OK. |
| Bought a new 6920 a month ago with the cage code on the barrel. When I took it apart to clean it I could not get the bolt back into the carrier without hitting it with the palm of my hand, it actually screwed up one of the gas rings. Long story short I had to take the carrier to my gunsmith who had to hone the carrier interior in the area where it collapses the gas rings. He said he has seen this before (on other carriers) and it was just a sharp edge. Carrier also has a piece of flash on the tail from machining the buffer detent channel that chewed up the buffer. I have two other older ones that are perfect. |

I wonder if this was another brand of rifle if the same issues would be so widely accepted as ok? It should work like it is supposed to without a break in period. Like guns that cost half of what that one did do straight out of the box. I don't see any issues. |

Like guns that cost half of what that one did do straight out of the box. The weapon doesn't need a break in period, it just needs the preservative cleaned off and lubed appropriately, not liberally, and will run perfect. There's no issue here and all, this is the same way we received weapons for the military, Colt and FN. William |

People need to stop inspecting their rifles with a microscope, and go shoot them. 50% of the "problems" on this forum are speculative worry from a new owner that hasn't even tried to fire their weapon. |

Like guns that cost half of what that one did do straight out of the box. Issues? You mean how it felt "rough?" Or that it might jam? The cure for that is to clean it, lube the heck out of it, and shoot it. Then see if any real "issues" arise. If they do, then feel free to indulge in some Colt-bashing. |

This thread got me thinking, is this black stuff normal on a Colt? I'm worried that I like how it smells. |

Not traditional pony like. I am somehow not surprised given the convergence of manufacturing processes and the competitive arena. I think the dis ability of Colt to serve the civilian market, combined with the advancement in CNC manufacturing, and the increased skill of .civ producers, has caught up with Colt. Personally, I want the Pony Brand to be the standard bearer for both quality and access. Tough market. Regarding the OP, you should just clean it, lube it, and then shoot it. It will probably be fine. Best Regards, Please let us know how it works out. Rick |
