A Brief History of the M16 / AR-15®

AR is an abbreviation for “Armalite Rifle.”

1959

Colt acquires manufacturing and marketing rights to the AR-10 and AR-15 from designer Eugene Stoner and Armalite. Eventually the AR-15 was adopted as the select-fire M16.

Mid 60’s

Colt gets a U.S. Department of Defense order of 85,000 M16s for Vietnam and 19,000 for the Air Force.

The M16A1 was updated with: - A new buffer to reduce the rate of fire
- Chrome-plated chamber and barrel
- Closed prong flash hider
- Forward assist
- New buttstock with cleaning kit
- 30-round magazine

Rifles were also produced by GM and Harrington & Richardson during the Vietnam War as well as outside the USA.

The M16A2 introduced: - Increased barrel diameter
- Rifling changed from 1:12 to 1:7 to accommodate a new 62 gr. bullet
- Modified rear sight
- Case deflector
- New round handguard
- Full-auto replaced with three-round burst

M4

The M4 was adopted based on a demand for a shorter, lightweight weapon. It features: - A 14.5” barrel
- Four-position telescoping stock
- Collapsed length under 30 inches
- Available in 3-shot burst or full-auto
- Equipped with a Picatinny-Weaver Rail System to replace the carry handle

Modern Sporting Rifle

The National Shooting Sports Foundation created the term “Modern Sporting Rifle” to introduce the AR-15 platform to the hunting market.
