The PWS FRC 3-port flat compensator in 1/2-28 (brand part no. 3FRC12A-5F) is a square-shoulder muzzle compensator from Primary Weapons Systems that doubles as a suppressor host. Primary Weapons Systems designed it to serve the Rearden Atlas suppressor mounting system, and it works with popular suppressors such as the BDE 556. Recoil reduction is its main job, and the three-port layout also controls flash by sending it away from your optic and line of sight. Mitigating recoil and muzzle rise helps with fast follow-up shots on the range and in the field.
