FN 509 Compensator Kit, Black/Flat Dark Earth - 20100809

The FN Compensator Kit is a quick-detach accessory designed for FN 509 and 509M pistols in 9mm. It features a toolless installation system that attaches to the proprietary non-threaded QD barrel, with V-style ports that reduce felt recoil and direct gases and flash away from the shooter's line of sight.
