    Sorry i'm not familiar with all the terms (extracting vs ejecting).

    It looks kinda like #2, but the next round is already trying to go into the chamber. So yes it is causing a jam as well as an extracting issue. I will take a pic next time it happens. I cleaned it pretty well today without removing the extractor from the bolt.

    and yes, the RO who works for spikes says its an Extractor issue.

    Extraction is jerking the fired (or unfired) case out of the chamber. Ejection is kicking it out of the gun. The extractor is the hook on the right of the bolt. The ejector is the plunger in the face of the bolt. A side point, beware, never, never depend on an extractor to remove a live round from the chamber, always look and or feel the chamber to make sure the unfired round actually did come out. Tragic accidents have happened when people assumed the extractor did it's job and removed the cartridge when in fact the cartridge was left in the chamber because the extractor failed. Back to the current issue: Do you have a fired case stuck in the chamber? This is a failure to extract. Do you have a fired case stuck in the bolt face or otherwise partially or fully still in the action? This is a failure to eject.

    Let me try and clarify or explain.

    1. The round must extract first before it can eject. That means that the round must fully exit the chamber and the ejector must kick it loose.

    2. I don't know how the RO (whomever that is) can say it is the extractor definitively. If the chamber is tight (and they are known to be) that will slow down or stop the extraction process which means that the bolt can still travel to the rear, strip another round and then attempt to fed it.

    3. If that isn't happening and it is simply not ejecting then you to change the ejector spring.

    The problem is that you have purchased a used upper of unknown origin (in that you don't know how many rounds were through it) you probably don't know if it truly functioned ever (most people sell uppers for one or two reasons, you guess what they are) and without having a competent person to examine it, you are simply chasing your tail.

    If you have a known quality BCG and it is doing the same thing then the issue is almost certainly the chamber. I would also throw that Spike's buffer in the trash and get a real one. Also, check the buffer spring, measure it and tell us how long it is.

    sounds like you have an excellent excuse to upgrade to a different upper, any excuse is good as my gun safe will attest. seriously though just buy a quality NEW upper by a reputable company and you will not be dissapointed. dont let this bad apple spoil your faith in AR15's. best of luck.

    Why are we putting all this effort into helping someone who hasn't put in a little effort to learn the parts of the gun? I'm done.

    What brand of barrel? Chrome chamber? .223 or 5.56mm chamber? How often cleaned? What brand of ammo is that brass?

    Dude, I've seen this on a number of occasions...that is CARBON build up/residue, it is NOT from Lacquer. News flash, you will see that on stuck brass cases as well, where there is no Lacquer.

    Oly Arms, who knows with them, most likely tight .223. Cleaned that day. American Eagle after a couple hundred rounds of late '90's geen lacquer steel.

    News flash for you Dude; it was lacquer, gooey, sticky, and didn't rub off on your hands. I've been doing this for a long time so those pics are from long ago.
