M16A1

The M16A1 was the second variant in the M16 series, following the original M16, an adaptation of the Armalite AR-15 rifle. The original M16A1 was released into service in 1964, and served in Vietnam. In 1969, it replaced the M14 as the U.S. standard service rifle. It fired a 5.56x45mm (non-NATO) round in 30 round magazines. Improvements over the M16 included a bolt-assist, improved bore, and the 30 round mag, as opposed to the original 20 round mag of the M16. As it did not have any rails, there are no accessories at all available for this gun. The fire settings were semi- and full auto.
