M16A2

The M16A2 was the next version of the M16, originally requested by the USMC, and adopted in the 1980s, replacing the M16A1. It was host to tons of new improvements. One important one was the switch to the new 5.56x45mm NATO rounds. Others included a spent casing deflector to protect left-handed shooters, new rifling, different barrel cover shape, an adjustable rear sight, and a new stock. Also, the full-auto mode was removed and replaced with a 3 round burst.
