bottom of the ejector squared off? Whachoomean?
All I know is that rounds that had fed just dandy before the "repairs" now get stuck. And that the ejector is visibly different. Even after not seeing it for a month, I could notice that it just didn't look the same as before.
When the cartridges jam, I can stick my finger in and push back on the ejector a little bit. I can feel something "give" and the cartridge flips up so the bullet is on level with the breach.
