What is meant by "failure to eject/stovepipe" in firearms?

"Failure to eject" or "stovepipe" specifically refers to a situation where a fired cartridge case does not fully exit the firearm after being discharged. This issue often arises during the cycling process when the firearm attempts to eject the spent casing after a round has been fired. In a stovepipe malfunction, the spent casing can become lodged vertically in the ejection port, resembling a stovepipe, which prevents the firearm from chambering the next round properly.

Understanding this term is crucial for firearm operators, as it highlights the importance of maintaining a clear ejection path and being able to diagnose and rectify these types of malfunctions quickly during practice or actual use. By recognizing that "failure to eject/stovepipe" relates directly to the ejection of fired cartridges, one can more effectively troubleshoot and ensure reliable firearm operation.
