The development of the M16A2 rifle was originally requested by the United States Marine Corps as a result of combat experience in Vietnam with the XM16E1 and M16A1.

How does the M16 work?
The M16's action works by passing high-pressure propellant gasses tapped from the barrel down a tube and into the carrier group within the upper receiver, and is commonly referred to as a " direct impingement gas system". The gas goes from the gas tube, through the bolt carrier key, and into the inside of the carrier where it expands in a donut-shaped gas cylinder. Because the bolt is prevented from moving forward by the barrel, the carrier is driven to the rear by the expanding gases and thus converts the energy of the gas to movement of the rifle's parts. The back part of the bolt forms a piston head and the cavity in the bolt carrier is the piston sleeve. It is more correct to call it an "internal piston" system."
How accurate is the M16?
The M16 rifle is considered to be very accurate. Its light recoil, high-velocity and flat trajectory allow shooters to take head shots out to 300 meters. Newer M16s use the newer M855 cartridge increasing their effective range to 600 meters. They are more accurate than their predecessors and are capable of shooting 1–3-inch groups at 100 yards. "In Fallujah, Iraq Marines with ACOG-equipped M16A4s created a stir by taking so many head shots that until the wounds were closely examined, some observers thought the insurgents had been executed." The newest M855A1 EPR cartridge is even more accurate and during testing "...has shown that, on average, 95 percent of the rounds will hit within an 8 × 8-inch target at 600 meters."
