How many rounds per minute is the cyclic rate of fire for the M16A2?

The correct answer is 800 rounds per minute for the cyclic rate of fire of the M16A2. This figure represents the theoretical maximum rate at which the weapon can fire in a continuous manner under ideal conditions. The M16A2 was designed with a focus on accuracy and controlled bursts rather than simply maximizing firepower, which is an important distinction from some other military rifles.

While the cyclic rate indicates the speed at which the weapon’s action can cycle and expel rounds when fully automatic, it's crucial to note that sustained fire at this rate without overheating or causing malfunctions would not be practical in a combat scenario. Additionally, the M16A2 is often used in semi-automatic or burst modes to enhance accuracy and conserve ammunition, which further illustrates the balance the design strikes between fire rate and effective use in the field.

Other options presented, while they may represent rates of fire for different firearms or theoretical figures, do not apply to the M16A2 and its design philosophy.
