So, was at the range yesterday and my bolt carrier got stuck at a position just a fraction of an inch before the round. Pulled the trigger and click, no bang. So i dropped the mag and and wracked back the carrier and the round didnt eject. So i wracked her forward again and it got stuck in the same position again, but this time stuck stuck. Finally gave it a REALLY good yank and the carrier came back and this time ejected the round. Worked fine after I cleared the jam, but it does have me a little concerned. Any idea as to what might cause this?
Nothing appears to be out of place, but i have had an occasional stove pipe due to some issue with the ejection pin.
