What three firing modes are available on the M16A4?

The M16A4 rifle features three specific firing modes: safe, semi-automatic, and burst. In the safe mode, the weapon is rendered inoperable, ensuring it cannot discharge unintentionally. The semi-automatic mode allows one round to be fired with each pull of the trigger, effectively allowing for controlled and precise shooting. The burst mode, on the other hand, enables the rifle to fire a predetermined number of rounds (typically three) with a single pull of the trigger. This combination allows the shooter flexibility in terms of firing speed and control, making the M16A4 a versatile weapon for various combat scenarios.

Other firing mode combinations do not accurately reflect the functionalities of the M16A4, which does not incorporate a fully automatic mode in its configuration as standard for the A4 variant, and thus highlights the importance of understanding the specific capabilities of the firearm in relation to operational contexts.
