1. Remington Outdoor
Number of guns made for the US market in 2014: 1.47 million
Estimates of the global revenue in 2014: $939 million
The second oldest company on this list with a tradition long 200 years, and the oldest in America is also the biggest gun manufacturer in the world. It all started back in 1816 when Eliphalet Remington II forged his first rifle barrel. The rest is history. Kidding aside, this company has come a long way to become what it is today. Their two models – Model 700 and Model 870 are among the best selling firearms of all time, which also says a lot about the Remington Outdoor’s dominance in the firearm production world.
