KAC QDC 3-Prong Flash Suppressor – 5.56

Designed by Knight’s Armament, this 3-prong flash eliminator delivers impressive flash reduction while doubling as the mounting base for KAC’s QDC-series sound suppressors. Its open-prong design is built to break up muzzle flash without the typical “tuning fork” ring common to similar devices. Each unit includes a shim kit to ensure proper timing during installation.
