Where is the safety selector located on the Mk-19 machine gun?

The safety selector on the Mk-19 machine gun is located on the sear assembly. This is a critical component within the firearm's firing mechanism, as the sear assembly is responsible for controlling the firing of the weapon. The safety selector, positioned here, allows the operator to engage or disengage the safety mechanism, ensuring that the weapon cannot be fired unintentionally.

Its placement on the sear assembly is particularly important because it directly interacts with the components that control firing, providing reliable mechanical safety by preventing the sear from releasing the bolt and allowing a round to be fired when the safety is engaged. Understanding this function is vital for safe operation and handling of the Mk-19.
