When is an M2 considered a hot gun?

An M2 machine gun is considered a "hot gun" when it fires 200 or more rounds in a two-minute period. This designation comes from the potential for overheating when the weapon is substantially overused in a short period, which can lead to malfunctions or even failures. This threshold helps ensure the weapon is used safely and maintains operational integrity.

Understanding the implications of a hot gun scenario is crucial for ensuring the reliability and longevity of the firearm, as excessive firing can affect both the weapon's performance and safety. This term is commonly used in military and firearm training to prevent overheating and manage ammunition consumption effectively.
