Founded in 2008 by firearm enthusiasts, Primary Weapons Systems (PWS) began by producing muzzle devices and testing their compensators across various rifle platforms, including M4s and AK-47s. Extensive high-round count testing revealed a striking difference in maintenance requirements, leading to the development of the PWS long stroke piston system. This innovative system preserves the core design of the AR-15 while significantly reducing maintenance needs in high-volume shooting and adverse conditions. Additionally, the integrated thread mount allows for easy suppressor attachment, enhancing versatility and performance.
