Primary Weapons Systems was formed by firearm enthusiasts in 2008. Our goal was to keep the core values of the AR15 design, while also lessening the need for maintenance by using a long stroke piston operating system. We take great pride in the fact that it is hard to find a customer who owns just one of our products. Once someone gives our rifles and accessories a try, they are hooked on the gentle push type recoil, high standards of craftsmanship, and reduced need for maintenance. (less)
