The AR-15 is the most popular rifle in America and one of the most popular in the world! It is estimated that there are between 15,000,000 to 20,000,000 ARs produced. Although many of them may have been lost in unfortunate fishing accidents, there are undoubtedly still many many millions of them in circulation.
This design was inspired by U.S. Patent #3,236,155 AR-15 Rifle (AR15 Semi-Automatic Weapon) which was patented in 1966 by its inventor Foster E. Sturtevant. This invention, titled firearm having an auxiliary bolt closure mechanism, was assigned to Colt’s Manufacturing Co Inc.
This patent changed the future for firearms in America, and it makes a really cool shirt design too!
