Inside America’s Robot-Run Gun Factory

We went inside SIG SAUER's headquarters in Newington, New Hampshire, where the company says it can build up to 100,000 pistols a month. Half the site machines parts like pistol slides, and the other half handles final assembly and range testing. Every firearm gets test-fired before it ships.

We saw robot-tended CNC machines turning bar stock into slides, robotic polishing cells, and the line building the Army's next-generation machine guns. According to SIG, that line once turned out more than 800 machine guns in a month. We also visited the SIG SAUER Academy to test suppressors designed to cut toxic fumes for soldiers.
