A little while back we had the opportunity to visit the extensive shop that is home to Vltor Weapons Systems. It's a huge facility, and gives Vltor the ability to do almost every part of a manufacturing process in house - including stamping, machining, welding, bending, laser engraving, and many different kinds of finishing. As a result, they make a pretty wide range of products. Their ARs are their best known work, but they also made the semiauto PKM receivers that came on the market a few years ago, plus AUG receivers for Steyr and complete 40mm grenade launchers for the military.
