What are the two modes of fire for the M16A2E3?

The M16A2E3 rifle is designed with two distinct modes of fire, which are semi-automatic and automatic. In semi-automatic mode, the rifle fires one round with each pull of the trigger, allowing for greater control and precision during engagements. This mode is particularly useful in scenarios where accuracy is critical and ammunition conservation is important. In automatic mode, the rifle continues to fire rounds as long as the trigger is held down, providing a higher rate of fire that can be effective in suppressing enemy positions or engaging multiple targets quickly.

This configuration enhances the versatility of the M16A2E3, making it well-suited for various combat situations. The ability to switch between semi-automatic for precision shooting and automatic for suppressive fire allows operators to adapt their tactics according to the operational requirements.
