The Primary Weapons Systems® FCS Compensator is a patented FCS compensator designed to be effective in any situation. This compensator’s primary function is to reduce felt recoil for improved accuracy and quicker follow-up shots while its unique port designs help to keep flash out of optics and line of sight for a cleaner sight picture. Plus, this compensator also reduces distracting overpressure that’s felt with many other compensators and features 4140 steel construction with a corrosion-resistant FNC LIFE HD treatment for long-lasting field service.
