The KAC 3-Prong Flash Eliminator is an extremely effective flash suppressor design that also serves as a platform for attaching a Knight's Armament Quick Disconnect Coupler (QDC) sound suppressor. This muzzle device was engineered to not only neutralize a rifle's flash signature, but also to eliminate the sympathetic ringing that is often associated with open prong flash hider designs.
