What is the difference between an AR-15 and an M16?

Next up, we have the M16. The M16 is a fully-automatic military rifle, which has been in use in the United States military since the Vietnam War. Technically speaking, an M16 is a variation of AR-15.

What is the difference between the Colt M16 and the M4?

The M16 was made by Colt to be little more than a fully automatic AR-15 but today, there are loads of configurations available for both rifles. The M4 carbine was later introduced, further blurring the lines between Stoner’s semi- and fully automatic black rifles. These two rifles are nearly identical in materials and construction.
