I’m a little confused, as you say the extractor keeps the case “shoved” against the opposite side of the receiver. But, the extractor is on the ejection port side. So it should be “shoved” out the EJECTION PORT. You know what I mean?

With the bolt open, the EXTRACTOR is on the side of the Ehection port. And the EJECTOR is on the “opposite” side. So I’m having trouble understanding how the case could be shoved to the wrong side?? You don’t have the Bolt Head on upside down, do you?
