Step-by-step explanation:
The M4 rifle has several different categories for malfunctions:
- Failure to feed: This occurs when the next round fails to enter the chamber properly. It can happen due to issues with the magazine or the ammunition.
- Failure to extract: This happens when the spent casing does not eject from the chamber after firing. It can be caused by a dirty chamber or a weak extractor.
- Failure to fire: This occurs when the trigger is pulled, but the round doesn't fire. It can be due to a faulty firing pin or a misaligned hammer.
- Failure to eject: This happens when the spent casing is not ejected from the rifle properly. It can be caused by issues with the extractor or a dirty chamber.
