A google search led me here after I had the same issue this afternoon with my rifle. I purchased a Remington R25 last December as a birthday splurge, and hasn't been able to take it out until today. 8 rounds fed and fired flawlessly, round 9 failed to eject, round 10 failed eject, and after removing round 10 and starting to remove the bolt the pin and spring fell out. The roll pin on mine had also walked free, I slightly opened it and had to give it some force to reinstall. Seems like there is a slightly larger issue with the quantity control at hand.
