1962: Colt gets US Department of Defense orders 85,000 M16’s for Vietnam and 19,000 for the Air Force.

Mid 60’s: The M16A1 was updated with a new buffer to reduce the rate of fire, chrome plated chamber and barrel, closed prong flash hider, forward bolt assist, new buttstock with cleaning kit, and a 30 shot magazine. Rifles were also produced by GM and Harington & Richardson during the Vietnam war as well as outside the USA.

1978: M16A2 was produced using an increase barrel diameter, rifling was changed from 1:12 to 1:7 to accommodate a new 62 gr. bullet, modified rear sight, case deflector, new round handguard, and full-auto was replaced with three round burst.

1994: M4 was adopted based on a demand for a shorter lightweight weapon. The M4 has a 14.5” barrel and a four position telescoping stock. Collapsed length is under 30 inches and weighs just over 5 1/2 pounds. Effective range is 600 yards. Available in 3 shot burst or full-auto. M4’s are also equipped with a Picatinny -Weaver Rail System to replace the carry handle
