What does the term 'cook-off' imply in firearm operation?

The term 'cook-off' in firearm operation refers to a situation where the barrel of the firearm becomes excessively hot due to continuous firing. This overheating can reach a point where the heat is sufficient to ignite the ammunition in the chamber, even when the trigger has not been pulled. This unintended firing occurs without the operator's intention and is a serious safety concern, particularly in military operations or during extended firing sessions.

Understanding 'cook-off' is critical for maintaining safety procedures and awareness while handling firearms. Recognizing the signs of overheating in the barrel can help prevent accidental discharges and ensure that proper cooling and maintenance protocols are followed.
