The M16A1 is fully automatic.
The M16A1 rifle was developed by the United States military as an improved version of the original M16. The design was primarily attributed to Eugene Stoner, who initially created the Armalite AR-15 rifle, which served as the basis for the M16 platform. The M16A1 was adopted by the U.S. military in 1967 and featured enhancements such as a forward-assist mechanism and a chrome-lined barrel to improve reliability.

It is called a magazine. To a firearms purist, a clip holds cartridges until they can be inserted into a magazine. ========================= If you wished to be more technical, it would be a "20 round detachable box magazine" (30 round magazines and any other magazine which fit the later M16A2 and M4 would also fit in an M16A1). The original models made by Colt were aluminum, and the follower was also made of metal (most current production magazines for the AR15 and other STANAG 4179 compatible rifles use plastic followers).
The M16A1 is the U.S. military designation for the AR-15 rifle built by Colt. The AR-15 itself was invented in 1957 by Eugene Stoner (1922-1997) while at ArmaLite.
The M16A1 assault rifle has two modes of fire: semi-automatic and fully automatic. As long as the trigger is held down, the weapon will continue to fire until the magazine is empty.
You will have to call Colt
The M16A1 is no longer used by any branches or special operation forces in the US Military. The M16A3, however, is used by some units in the US Air Force, particularly security forces. It is not the standard-issue rifle for any branch or special forces.
The effective range of the M16A1 rifle is approximately 550 meters, but it can technically fire up to around 3,600 meters. However, accuracy and effectiveness decrease significantly at longer distances.
