| I have a Colt 9mm F/A that I'm having problems with, I can fire off a string of 7-9 rounds and then I get a empty case and a full case stuck in the chamber area. I cleaned it and tried different rounds with the same results the only thing I didn't take apart was the extractor out of the bolt. Anyone have any ideas on where I should start looking |

^ ejector. it needs to ride as high and tight towards the center of the bolt as it can (within the ejector groove obviously). This. It's classic. Your ejector is just a little off-otherwise you'd get only a single round fired before it choked. The ejector has to be as close as possible to the ejector channel in the bolt, both laterally and vertically. SBR7_11 posted some great pictures of this in the 8th post down in this thread. |
| I checked the ejector and it looked OK it's a factory Colt so the ejector is pinned into the receiver and it seemed tight with no movement. I did take out the extractor and there was a ton of crud in there. I cleaned it but haven't been able to shoot it yet. By the looks of how much stuff was in there I don't think that it has ever been taken apart. I have my fingers crossed that cleaning the extractor will fix it. After I get a chance to shoot it I'll give an update. |

The ejector doesn't "move" from where it's pinned in (whether with a factory Colt "everything's pinned in" or a Rock River removable block), but it does BEND. It moves left/right and up/down, depending on how the lower is handled. Look VERY closely at whether or not the ejector is as close as humanly possible to the slot in the bolt for it. Gently "encourage" it into that spot until it actually rubs, then give it a tiny touch away from the bolt. Do this for both left/right AND up/down, as the face of the ejector has to be parallel with the bolt face for it to work properly. |

Pull the extractor and see if there's crud built-up in the channel. Also check that your ejector is riding close enough to the bolt. There's a thread somewhere in the archives that addresses the ejector issue, I'll see if I can dig it up. Chris , you hit that nail on the head
