FN America Compensator Kit Fits FN 509, Black - Reliable Compensator Kit for Improved FN Performance - 20-100806

Elevate your FN 509 with the pinnacle of performance using the FN compensator accessory kit. Originally featured on the FN 509 CC Edge, this compensator boasts a unique quick-detach (QD) design, enabling hassle-free installation and removal from the proprietary non-threaded QD barrel within minutes, no need for gunsmithing or factory service. The FN compensator effectively reduces felt recoil with v-style ports on both sides, directing gases and flash away from the shooter's line of sight. The outcome is a smoother, more controlled shooting experience that maintains a consistent sight picture shot after shot.
