This mechanism is a component found on select M14 rifles that allows the operator to choose between different firing modes. Specifically, it facilitates the selection of either semi-automatic fire, where one round is discharged per trigger pull, or fully automatic fire, where the rifle continues to fire as long as the trigger is depressed and ammunition is available. Its presence dramatically alters the weapon’s operational capabilities.
The implementation of such a feature significantly increases the rifle’s firepower, enabling rapid engagement of multiple targets or providing suppressive fire. However, this enhanced capability comes with trade-offs, including a higher ammunition consumption rate and reduced control over the weapon during sustained fire. Historically, the inclusion of this selector has been a point of contention due to concerns regarding controllability and potential misuse.
