Upgrade your FN pistol with the cutting edge of performance with the FN Compensator Accessory Kit. First introduced on the FN 509 CC Edge, the compensator’s unique quick-detach (QD) design allows for toolless install and removal from the proprietary non-threaded QD barrel in a matter of minutes, no gunsmith or factory service required. The FN Compensator significantly decreases felt recoil and features v-style ports on either side that vector gases and flash out of the user’s field of view. The result is a shooting experience that is flatter and more controlled, allowing users to maintain a consistent sight picture from shot to shot.
