The M16
The M16 is a gas-operated, air-cooled, magazine-fed, shoulder-fired rifle. It has a high rate of fire and is effective at long range. It is the standard rifle of the United States Army.
History
In the early 1960s, the United States Army began looking for a new rifle to replace the aging M14. The new rifle had to be lighter, more accurate, and more reliable than the M14. After a series of tests, the Army selected the M16 as its new standard-issue rifle.
The M16 entered service in 1963 and was first used in combat during the Vietnam War. The rifle quickly proved itself to be a reliable and effective weapon, and it has since been used by the United States military in a number of conflicts. The M16 is currently the standard-issue rifle of the United States Army and Marine Corps.

The M16 is a gas-operated, air-cooled, box magazine-fed, shoulder-fired rifle with a fully automatic mode and a three-round burst mode. It has a chrome-lined bore and chamber and is capable of firing the full range of 5.56x45mm NATO ammunition, including the M855 “green tip” penetrator round.

History
The M4 is a gas-operated, magazine-fed, selective fire, shoulder-fired weapon with a collapsible stock. It is a shorter and lighter variant of the M16A2 assault rifle.
The M4 was first developed in the early 1990s as a replacement for the original M16 in close quarters combat (CQC) environments. Since then, it has been adopted by the United States Armed Forces and is now used by several Special Operations units as well as by many state and federal law enforcement agencies.

M16 vs M4
There are two main types of rifles used by the U.S. Army: the M16 and the M4. Both are gas-operated, air-cooled, magazine-fed rifles that fires rifle cartridges. The M16 is the standard rifle for the U.S. Army, while the M4 is a shorter and lighter version of the M16.
The M4 is generally used by troops who need a more compact weapon, such as special forces and aircraft crews. The M4 is also easier to control in full-auto mode than the M16, making it more effective in close quarters combat.
There are some other differences between the two rifles, such as the fact that the M4 has a three-round burst mode while the M16 does not, but overall they are very similar weapons.
