The AR-15 is one of the most recognizable and debated firearms in the world. But what exactly does the "15" in its name signify? Contrary to popular belief, it doesn't represent a caliber, a specific feature, or a year of manufacture. Instead, it's a historical artifact linked to its developmental lineage.
The ArmaLite Rifle and its Evolution
The "AR" in AR-15 stands for ArmaLite, the company that originally designed and developed the rifle. ArmaLite, a subsidiary of Fairchild Engine and Airplane Corporation, created the AR-10, a larger-caliber rifle, in the 1950s. This rifle's design served as the blueprint for the AR-15.
The "15" designation wasn't randomly assigned. It represents a model number within ArmaLite's internal product classification system. It distinguishes this specific design from the AR-10 and other models within their arsenal. While the exact reasoning behind the numeric designation remains somewhat opaque within ArmaLite's internal documentation, it likely reflects a chronological or internal project code.
From ArmaLite to Colt: A Shift in Production and Recognition
ArmaLite eventually sold the rights to manufacture the AR-15 to Colt's Manufacturing Company. Colt significantly refined the design and brought the AR-15 to widespread recognition, particularly among military and law enforcement agencies. Colt continued to use the AR-15 designation, further solidifying its place in the firearm's identity.
Debunking Common Misconceptions
It's crucial to dispel some common misconceptions surrounding the "15":
- It's not the caliber: The AR-15 typically fires the .223 Remington or 5.56x45mm NATO cartridge. The "15" is unrelated to this ammunition.
- It's not a year: While the design originated in the mid-20th century, the "15" doesn't represent a specific year of development or production.
- It's not a feature: The number isn't associated with any specific component or feature of the rifle.
The AR-15 Today: A Continued Legacy
The AR-15's design continues to influence modern firearm development. While Colt's original AR-15 has evolved and countless variations now exist, the fundamental design principles remain largely consistent. Understanding the origin of the "15" helps clarify the rifle's historical context and sheds light on its enduring presence in the world of firearms.
