From Guns & America:
Jim Corbet was a building contractor with way more free time than business in 2011, as the fallout from the subprime mortgage crisis took hold in his hometown of McCall, Idaho.
Corbet was also an amateur machinist and firearms enthusiast and he noticed fellow shooters gravitating toward one semi-automatic rifle in particular – the AR-15. So he set up shop in his garage and started tinkering with designs.
Eight years later, his business, Unique ARs, employs 10 people at a warehouse factory that churns out thousands of AR-15 rifles and accessories each year destined for customers all over the country and the world. It’s one of the scores of companies, large and small, that have helped make the AR the most popular rifle in America. As the name suggests, Corbet’s company specializes in custom rifles built to individual specifications.
“It’s the most universal rifle platform that’s ever been manufactured,” Corbet said. “Because there is such a standardized way it’s been built, it can be reconfigured very easily.”
