I’m assembling an AR from various upper parts. While checking head space, i decided to just see if my extractor would grab a case rim. I already had the bolt apart anyway. The notch will not allow a case rim of 223 to enter.
Maybe it’s not supposed to, so I tried a different bolt from another rifle. This one catches and holds firm. It looks like I have a narrow extractor groove. Is this common? I’m reluctant to try to chamber and eject a round. I don’t want a live round stuck in the chamber.
