The FN Compensator significantly decreases felt recoil and features v-style ports on either side that vector gases and flash out of the users 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. FN Compensator Accessory Kit is available in models compatible with FN 509 Standard Compact models.
