What is an AR-15?

I was enjoying a novel the other day until a character switched an AR-15 (pictured above) into fully automatic mode and started blasting away at bad guys. Thing is, AR-15s don’t have a full-auto mode. It’s time to clear the waters, because this is only one of the misconceptions.

AR-15s Are…

  • Semi-automatic rifles – Pull the trigger once and the rifle will shoot one time. There are no fire modes to switch in and out of, that’s all it does. Fully automatic is different from semi-automatic in that one pull of the trigger can equal multiple shots fired consecutively.
  • Both a model and a type – This seems tricky, but it’s not too confusing. Colt is the only company that can say it makes a genuine AR-15 (the model). However, other companies make AR-15 clones and AR 15 accessories and put their own spin on them. In both cases, you could write AR-15 (or just AR) and still be accurate.
  • Customizable – AR-15s come ready to attach any number of accessories, which is part of the reason they’re popular.
  • Old – For as recent as AR-15s seem, Eugene Stoner actually designed the first one in the 1950s. The .223 caliber ammunition most often used in AR-15s (there are others) is also nothing new.

AR-15s Are Not…

  • Assault rifles – The “AR” stands for Armalite Rifle, not assault rifle. An assault rifle is capable of switching between different modes of fire, such as semi-automatic and fully automatic. The AR-15 can’t do that, it’s stuck in semi-auto mode.
  • Capable of using clips – AR-15s use magazines, not clips.

Why the Confusion? Blame the M16

The AR-15 shares a common lineage with the M16, the iconic U.S. military rifle in use since the 1960s. They both look similar, but appearances are often deceiving when it comes to firearms. The M16 can switch between modes of fire, from semi-auto to full-auto and back again. This is an M16 (image via Shutterstock).

M16

In the case of the book I was reading, this is where the author tripped up. The character’s firearm was called an AR-15, but functioned like an M16. The author in this case should’ve picked one and stuck with it, although the AR-15 is the more likely choice given the civilian character’s circumstance. M16s are hard to come by outside of the military.

  1. A friend bought one of these ‘cause he said the gun dealer told him he couldn’t sell him an M-16, and these are used by the Canadian Forces.

    Looks like he was mostly right – they actually use the Colt Canada C7 rifle, which is a variant of the AR-15.

    All I can tell you for sure is an AR-15 is a weapon that can assault anyone in sight by the sound alone.

    • Thanks, Steve. From what I can tell, the M-16 and the C7 are identical, except for the naming conventions of the U.S. and Canadian militaries. And you wouldn’t be able to buy an M-16 in the States, either, since they can fire in a fully automatic mode. No U.S. civilian can buy any full auto made after May 19, 1986.

      AR-15s are still popular here, though, mostly for shooting sports and hunting. They’re more for enthusiasts than self-defense, not all that different from run-of-the-mill .223 rifles.

  2. When I went through U S. Army BASIC training in 1988 and we had COLT AR-15 rifles. They fired in both semi and full auto modes. ( AR-15 not M-16 was on the weapons.) Just saying.
