FN 509 Midsize Compensator Accessory Kit

The FN® 509 Midsize Compensator Accessory Kit is a cutting-edge upgrade for your FN 509 pistol and is designed for improved performance. The compensator 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 compensator is machined from stainless steel with a corrosion-resistant PVD finish and features a quick-detach (QD) design that allows for toolless installation and removal from the included proprietary non-threaded QD barrel. No timing or shims needed! Includes FN 509 Midsize Compensator and 9mm barrel.
