What does the M249 applied safety do?

Explanation:
The applied safety on the M249 is designed to block the sear. When engaged, it prevents the sear from releasing the hammer, so pulling the trigger cannot fire the weapon. The bolt can still be cycled (e.g., for clearing a jam or charging), and the action of the safety itself isn’t about locking the bolt or disconnecting anything else. So the safety’s job is to stop the hammer from dropping by blocking the sear, keeping the firearm on safe regardless of trigger movement.
