There is a lot of confusion about the AR-15. Most people today think the
AR-15 is the semi-automatic civilian version of the select fire military
M-16. In fact both are AR-15s. In the late 1950s the military was looking
for a lightweight replacement for the venerable M-1 Garand which was the
standard battlefield rifle of the US military in WWII. The M-14 was a
fully-automatic version of the M-1 but the recoil proved too powerful for
most soldiers to hold on the target when firing in full auto. It was not
too much of an exaggeration to say that by the time the fifth round was
fired it was an anti-aircraft gun. Armalite developed a the select-fire
AR-15. It was much lighter than the M-1 or the M-14 and because it fired a
smaller round, 5.56mm as opposed to 7.62mm, soldiers could carry more
rounds without increasing weight. At first the Army balked but Curtis
Lemay was impressed by it and adopted it for the Air Force. Eventually is
became the standard battlefield rifle for all the branches and was
designated the M-16. Armalite sold the patent to Colt who produced it for
the military. Eventually they offered a semi-auto version to the civilian
market and it has since been manufactured by a number of gunmakers. Today
if you say AR-15, most people think you are referring to the
semi-automatic civilian version but police departments have adopted both
the semi-auto and select fire versions of the AR-15. It is the favored
weapon for most SWAT teams.
