Product Description The FN America 20100808 Compensator Accessory Kit is a precision-engineered performance upgrade purpose-built for the FN 509 Midsize pistol. Machined from stainless steel and coated with a durable black PVD finish, this compensator kit is built to withstand hard use across a wide range of standard and self-defense loads while still utilizing the factory FN 509 recoil spring. First introduced on the FN 509 CC Edge, the compensator features a unique quick-detach (QD) design that allows for toolless installation and removal from the proprietary non-threaded QD barrel in just minutes, requiring no gunsmith or factory service. The compensator significantly decreases felt recoil and reduces muzzle rise by up to 25%, with v-style ports on either side that vector muzzle gases and flash out of the shooter&';s field of view. The result is a flatter, more controlled shooting experience that helps maintain a consistent sight picture from shot to shot, whether at the range or in a competitive environment.
